Ultra-Low Pressure Sensor - LP Series

What you get with the LP Series is a sensor for very low pressures that is easy to solder to a PC board and connect to standard tubing. We offer it fully compensated, saving you calibration time and equipment on the assembly line. It is also available uncompensated for lower cost. Once in the application, the LP Series performs with excellent linearity, hysteresis, and stability.

FAQ

View All

What is the highest and lowest amount of pressure that your sensors can measure? Show Answer

Our sensors measure as low as 0.04 psi and as high as 15,000 psi.

What are “pressure sensor components”? Show Answer

Pressure sensor components are die or chips and simple assemblies of the same. Transmitter and transducers are fully packaged and conditioned/calibrated sensors.

What is “hysteresis”? Show Answer

This relates to the output of the die at increasing and then deceasing pressures (or temperature cycles) throughout the pressure range or span. In general, the output is compared against itself for consistency. Hysteresis is expressed as a percent of full-scale output (FSO).
