Measure your equipment’s pressure and send the data directly to a development board or single-board computer. Also known as transducers, these transmitters convert pressure into an electrical I2C signal and transmit it to your board by connecting a cord (not included) with a Qwiic connection. Transmitters connect directly to your machinery via tubing (not included), letting you monitor activity such as gas tank pressurization and liquid fill level.

Unlike other pressure transmitters that measure the difference between your system and the atmosphere, these transmitters give measurements relative to zero pressure—regardless of altitude or temperature. They will only provide accurate readings within the rated pressure range.

At least four times as accurate as standard pressure transmitters, these transmitters are ideal for use in laboratories and analytical testing applications. All come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. Also known as transducers, pressure transmitters 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 transmitter's pressure range and output signal. Transmitters will only provide accurate readings within the rated pressure range.

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.

All transmitters are CE marked, meaning they meet European safety standards. NEMA 4X rated transmitters are for use in washdown and corrosive environments. IP67 rated transmitters are protected from temporary submersion during washdowns.

Used with pumps, cooling systems, and other liquid applications, these transmitters remotely measure the difference in pressure between two inputs. They are also known as transducers. These transmitters 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. You’ll often see them used to indicate a filter is clogged.

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. 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.

IP66 rated transmitters are dust tight and protect against washdowns. NEMA 4X rated transmitters protect against weather, washdowns, and corrosion.

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.

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. All come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. 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. Transmitters will only provide accurate readings within the rated pressure range.

Rated IP67 and NEMA 4X, these transmitters seal out dust and water from temporary submersion. All are CE marked, so they meet European safety standards.

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.

Install these gauges through the top of your tank to monitor diesel fuel, fuel oil, or gasoline level.

Gauges with center shafts should reach ½” to 1” above the bottom of your tank to prevent it from touching the bottom.

Gauges with float rods are UL Listed for flammable liquids. For shallower tanks, cut the float rod ½” to 1” shorter than your tank depth to prevent it from touching the bottom.

Optional dials with output show fuel level at the source or use the two wires to connect them to monitors, dashboards, or other receivers for remote monitoring. They are also known as fuel senders.
