1 Introduction

MPM4736/4706 transmitter is a highly precise and stable digital

transmitter for the pressure/level measurement. This product utilizes the

highly reliable pie zoresistive OEM pres sure sensing eleme nt and the hi gh

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 v ia an R S485 i nterface . The t ransmitte r consume s ve ry low

power and automatically enters standby mode when not communic ating,

and the power consumption at standby mode is as low as 10uA.
