High-precision, high-stability intelligent digital pressure transmitter

Background

MPM/MDM4760 is a high-precision, high-stability intelligent digital pressure transmitter designed by Micro Sensor. After years of market test, it has been upgraded and improved:

1. The circuit and program algorithm are upgraded which improves the accuracy. Within the compensation temperature range, the typical error in full temperature range is better than 0.1%.
2. Power consumption battery-powered MPM4760 series is optimized. It can measure pressure at real-time with LCD display more than 3 years;
3. RS485 ModBus RTU communication protocol now is optional.
4. Four and a half digits LCD display with backlight is available.

Features
