Microsensor Digital Pressure Transmitter MPM4736 Series

The Pressure Transmitter for Industrial automation.

MPM4736 digital pressure transmitter is a highly precise and stable digital transmitter for the pressure measurement. This product utilizes the highly reliable piezoresistive OEM pressure sensing element and the high precision digital processing circuit, coupled with a dedicated algorithm, the transmitter is capable of high precision measurement. The product supports the measurement of both pressure and temperature and communicate via an RS485 interface. The transmitter consumes very low power and automatically enters standby mode when not communicating, and the power consumption at standby mode is as low as 10uA.

Main Features

• Extremely low consumption and available for auto stand-by mode
• Integrated temperature measurement
• Digital compensation and >non-linearity correction
• Suitable for networking
• Stainless steel housing, compact and light
• Customizable
