Absolute Pressure Transmitters

Monitor and control pressure in portable HVAC systems, hydraulics, and oil and gas equipment. 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. Also known as transducers, they convert pressure into an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers (PLCs), and motor speed controls. 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.

All transmitters are rated IP67 for protection from dust and temporary submersion during washdowns.

4 mA to 20 mA Output Current—Wire Lead Connection

Image of Product. Front orientation. Contains Annotated. Pressure Transmitters. Absolute Pressure Transmitters, 4 mA to 20 mA Output Current—Wire Lead Connection.

Transmitters with output current 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.

NEMA 4X Enclosure Rating—Transmitters that are rated NEMA 4X also protect against weather and corrosion.

Handheld High-Vacuum Gauges

Check the vacuum levels in high-vacuum pumps, valves, and chambers with these compact gauges. Use a ring and clamp (both sold separately) to connect them to another quick-clamp high-vacuum fitting, also known as KF, QF, and NW fittings. The digital display shows measurements in torr, mbar (millibar) and hPa (hectopascal).

Absolute Pressure Gauges


	Bottom Connection

Unlike other gauges that measure the difference between your system and the atmosphere, these give measurements relative to zero pressure. They’re often used in laboratory applications, and they are barometrically independent.

Stainless Steel Case—Stainless steel gauges have excellent corrosion resistance, so they can be used with more corrosive liquids and gasses than gauges with a brass connection and aluminum case.

Torr—Gauges with a Torr scale are also known as Torr gauges.

Absolute Pressure Transmitters for Development Boards

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.
