Specifications - Microsensor MDM490 Operation Manual

Thanks for your using products from MICROSENSOR. MDM490 precise
piezo-resistive transmitter is one of precise instruments. We suggest you to read
this manual carefully before use.
1 Introduction
MDM490 precise piezo-resistive transmitter is a differential pressure
measurement device with compact size. The transmitter using a differential
pressure sensor and special amplified circuit, through stability and reliability
experiments, can provide standard 2-wire 4mA～20mADC and 3-wire 0/1V～
5VDC 、0mA～10mA/20mADC signal output by external power supply
24VDC, as well zero and span compensation in the wide temperature range.
The parts being contacted with the media are the stainless steel materials and
viton. The differential pressure transmitter can be used in vary industry
processing control and differential pressure, flow and level measurement, etc.
The product is manufactured in conformity to License for Manufacturing
Measurement Instrument Shaanzhi No. 03000112 of P. R. China. Products
measurement tools type approval No. 15F139-61.
