About Pressure Transmitters

For Use With: Air, Diesel Fuel, Gasoline, Hydraulic Fluid, Water
Accuracy: ±1%
Pipe Connection: NPT Male
Housing Material: 316L Stainless Steel
Connection Material: 316 Stainless Steel
Temperature Range: -40° to 255° F

For use in harsh environments, these transmitters are rated NEMA 4X for protection from washdowns and corrosion. Also known as transducers, they convert 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 vacuum or control equipment. As vacuum decreases, the output signal from the transmitter will increase. For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the vacuum range and output signal of your transmitter. Transmitters will only provide accurate readings within the rated vacuum range. Maximum pressure is the maximum spike in pressure a transmitter can withstand without damage.

4-20mA current output transmitters connect 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.

DC voltage output transmitters connect using three wires—two wires into the power supply and a separate wire that sends a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.

High-Accuracy Vacuum Transmitters

For Use With: Air, Diesel Fuel, Gasoline, Hydraulic Fluid, Water
Accuracy: ±0.25%
Pipe Connection: NPT Male
Housing Material: 316 Stainless Steel
Connection Material: 17-4 PH Stainless Steel
Temperature Range: -5° to 180° F

At least four times as accurate as standard vacuum transmitters, these transmitters sense vacuum at an accuracy of ±0.25%. They are commonly used in laboratories and testing applications. These transmitters, also known as transducers, convert 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 vacuum or control equipment. As vacuum decreases, the output signal from the transmitter will increase. For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's vacuum range and output signal. Transmitters will only provide accurate readings within the rated vacuum range. Maximum pressure is the maximum spike in pressure a transmitter can withstand without damage.

These transmitters 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.

With an accuracy of ±0.25%, use these transmitters in applications that require highly accurate measurement of both pressure and vacuum, such as activating vacuum pumps. They convert 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. As pressure increases, the output signal from the transmitter will increase. 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.

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. Transmitters will only provide accurate readings within the rated pressure range. Maximum pressure is the maximum spike in pressure a transmitter can withstand without damage. All transmitters meet IP66 and NEMA 4X for use in washdown environments and have a hastelloy diaphragm to resist harsh chemicals.

Monitor pressure from a distance with these remote displays. They support five different input mA current and DC voltage signals, so they can be used with most common transmitters. Settings are saved even when power is turned off. To prevent tampering, they have a lockout feature that requires a password to modify settings. They are rated NEMA 4X for protection from corrosion and washdowns.

The display with two SPDT (single pole, double throw) relays can be used to send control signals for process-control systems.
