ACE 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

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.
