Differential Pressure Transmitters with Dial Indicator for Liquids

Image of Product. Front orientation. Differential Pressure Transmitters. Differential Pressure Transmitters with Dial Indicator for Liquids.

View readings at the source with the dial indicator or remotely using a receiver—these transmitters measure the difference in pressure between two inputs in liquid applications. The dial indicator operates independently of the transmitter and shows differential pressure in real time for troubleshooting. Also known as transducers, these transmitters convert pressure to an electrical signal that is interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls. You’ll sometimes see them used to indicate a filter is clogged in a pump or cooling system. Rated NEMA 4X, these transmitters protect against dirt, washdown, and corrosion. They are also rated IP65 for protection from dust and rinsing. All are CSA certified, so they meet Canadian safety standards.

For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's differential pressure range and output signal. As differential pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range. Connect them using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices.

Submersible Liquid-Level Transmitters


For Liquids	For Liquids with Solids

Best for measuring liquid levels in applications where traditional mounting is difficult, these transmitters sit at the bottom of your tank. They sense liquid levels by measuring the pressure from the weight of the liquid above them. These transmitters continuously send measurements, so you can monitor the status and manage components in your system. Also known as level loggers, level sensors, and pressure transducers.

For Liquids with Solids—Transmitters for liquids with solids have sink weights that keep the transmitter in place in applications with moving solids or agitated liquids.

Easy-Setup Pressure and Vacuum Transmitters

These transmitters automatically compensate for error introduced into both pressure and vacuum measurements by vibrations as well as temperature fluctuations, so you do not need to program corrections for these factors into your receiving device. Use the keypad to set the pressure range, choose the unit of measure, and zero the transmitter. Transmitters convert pressure and vacuum to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment. They will only provide accurate readings within the rated pressure or vacuum range.

All transmitters meet IP66 and NEMA 4X for use in washdown environments and have a Hastelloy diaphragm to resist harsh chemicals.

These transmitters typically connect using two wires to send a 4-20mA current output. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. They can also be configured using three or four wires.

Precision Liquid-Level Gauges for Tanks

Style B

Using inches or centimeters instead of common levels, such as full or empty, these gauges are more precise than standard gauges when measuring liquid levels. While most gauges are designed for one tank depth, these have a float attached to a cable, so they work with any tank up to the maximum depth listed.

Style B—Style B gauges have a dial with a small hand that displays feet and a large hand that displays inches. They come with labels to mark high and low levels on the dial face.

Hazardous-Location Easy-Setup Pressure Transmitters

Safely monitor liquid, gas, and steam pressure in hazardous locations with these transmitters. They meet NEC safety standards, so they protect against an explosion where flammable gases and vapors are present.

These transmitters automatically compensate for error created by vibration or fluctuations in temperature, so there’s no need to account for these factors when programming your receiving device. Use the keypad to set the pressure range, choose the unit of measure, and zero the reading. They convert pressure into an electrical signal and send it to your receiving devices, such as remote displays, programmable logic controllers (PLCs), and motor speed controls to monitor pressure or control equipment. Transmitters will only provide accurate readings within the rated pressure range.

All transmitters are rated IP66 and NEMA 4X to protect against dirt, dust, washdowns, weather, and corrosion, and their Hastelloy nickel connection resists harsh chemicals.

These transmitters typically connect using two wires to send a 4-20mA output current. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. They can also be configured using three or four wires.

High-Accuracy Differential Pressure Transmitters

At least twice as accurate as standard transmitters, these transmitters sense differential pressure at an accuracy of ±0.25%. Use them in laboratories or testing applications where the difference in pressure between two points needs to be measured with high accuracy. These transmitters are often used to indicate a filter is clogged or help you maintain a certain pressure in pumps, HVAC, cooling, and other air and liquid systems. They convert differential pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment. All transmitters are rated NEMA 4 for protection in washdown environments.

For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the pressure range and output signal of the transmitter. As the differential increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range. Connect them using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices.

Hazardous Location Easy-Setup Pressure and Vacuum Transmitters

Used in hazardous locations, these transmitters safely convert pressure and vacuum into an electrical signal to measure liquids, gases, and steam. NEC rated for safety, these transmitters are explosion proof, so they can be used in environments containing flammable gases and vapors.

These transmitters automatically compensate for error in both pressure and vacuum measurements caused by vibrations and temperature fluctuations, so you don’t need to separately program corrections into your receiving device. Use the keypad to set the pressure or vacuum range, choose the unit of measure, and zero the transmitter. These transmitters convert pressure and vacuum to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers (PLCs), and motor speed controls, to control equipment or monitor pressure. Transmitters will only provide accurate readings within the rated pressure or vacuum range.

Rated NEMA 4X and IP66, they protect against dirt, dust, rust, harsh weather, and washdowns, and their Hastelloy connection resists corrosive chemicals.

These transmitters commonly connect using two wires to send a 4-20mA current output. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. Three- and four-wire configurations are also possible.
