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.

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. Those that are rated NEMA 4X also protect against weather and corrosion.
Transmitters with current output 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.
Transmitters with voltage output 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.

Absolute Pressure Gauges
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.
Gauges with a Torr scale are also known as Torr gauges.
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.

M12 Plug
Continuously monitor your air cylinder rod’s position and turn the cylinder on and off with a single component. These transmitters send positioning data to computers, programmable logic controllers (PLCs), and human-machine interfaces (HMIs). They're often integrated into automated systems for tasks such as timing when certain steps of your process should take place and verifying dimensions for quality control. Rated IP67, these transmitters withstand temporary submersion.
Press the buttons on the switch to toggle between voltage and current outputs. These transmitters have a plug that connects to cables with a socket (not included) so you can quickly connect and disconnect the switch.
