PCM303 Universal Pressure Transmitter Features ■ SS316L diaphragm structure ■ High accuracy, all stainless steel structure ■ Small size and light weight ■ Strong anti-interference, good long-term stability ■ Diversified formal structures, easy installation and use ■ Wide pressure range, can measure the absolute pressure, gauge pressure and sealed gauge pressure ■ Anti-vibration, shock resistance ■ Zero, full span adjustable Process control Aerospace Automobile and medical equipment Pipeline system Notes: 1 Do not touch the diaphragm with hard objects, which may cause damage to the diaphragm. 2 Please read the Instruction Manual of the product carefully before installation and check the relevant information of the product. 3 Strictly follow the wiring method for wiring, otherwise it may cause product damage or other potential faults. 4 Misuse of the product may cause danger or personal injury. Product overview PCM303 economic pressure transmitter adopts diffused silicon pressure sensor as pressure sensing element. Through internal ASIC, the millivolt signal of sensor is transmitted into standard current signal. PCM303 can be directly connected with computer interface card, control instruments, intelligent meters or PLC etc. conveniently. Long-distance transmission can use current output. PCM303 features with small size, light weight, all stainless steel sealing structure and ability to work in corrosive environments. The product is easy to install and has extremely high vibration and shock resistance. PCM303 is widely used in process control, aviation, aerospace, automobile, medical equipment, HVAC and other fields.
