The Setra 201 is a high-precision, low-cost pressure sensor for measuring very low gauge pressure differentials. The product’s leak-free design with all-welded, O-ring-free construction is ideal for particularly demanding low-range applications.

The process connection of 201 is suitable for pressure media compatible with stainless steel and 600 series Inconel.

Ultra-low differential pressure sensor

Setra 201’s patented variable capacitance sensor design combines minimal simplicity, precision, and excellent thermal stability. It uses a chrome-nickel diaphragm and an insulated electrode. The working principle is that the capacitance value of the diaphragm changes correspondingly with the pressure rise. Then, it is converted into a fully modulated linear current output signal by detecting the change in the capacitance.


Designed for rugged durability, overvoltage capability up to 45 PSI (310 kPa), and a wide operating temperature range, the Setra 201 sensor is ideal for demanding applications.
