Merit Sensor TRVF Series

The TRVF Series is a fully compensated harsh-media, digital I2C and analog output, pressure-sensor package. It is designed to handle today’s toughest pressure-sensing environments with a temperature range of -40°C and 150°C. The unique pressure port isolates onboard electronics, the three wetted materials (silicon, glass, and ceramic) enable the TRVF Series to withstand a variety of harsh media.
The TRVF design isolates the the FR-4 high TG substrate mechanical stress from the MEMs die avoiding possible offset shifts caused during the manufacturing process. The spring contacts make the customers’ assembly process easier and faster.
