Description
■ Features
The VPC81MA pressure transmitter is a high stability pressure transmitter that uses a specific ASIC signal conditioning chip and a silicon pressure sensor with diffuse high performance SS316L diaphragm.
The internal specific ASIC circuit transforms the millivolt signal into a standard voltage, current or frequency signal. It is easily connected to PC interface cards, control instruments, smart meters or PLC. Its compact, light design and stainless steel seal structure allow you to function in corrosive environments.
1. Specific High Performance Asic Circuit
