4-20mA, 0.5-4.5V, 0-5V Pressure Sensor


ACE pressure sensor series are designed as a transmitter capsule, There are three function modules embeded in a 316L stainless steel housing.
1) Pressure module–Utilizing silicone oil to transfer pressure from the 316L stainless steel diaphragm to a MEMS pressrue die.
2) ASIC module–Amplification and temprature compensation for pressure siginal
3) EMC module–Protection for the whole electric circuit

0-5V Pressure Sensor

The transmitter capsules themselves are ideally suited for embeding in application-specific systems.
Various amplified output with 4~20mA, 0.5~4.5V, 0~5V are avaliable, Also digital output of I2C or SPI could be provided based on request.
