original honeywell STD725 pressure transmitter with display 4-20mA output

product description

HoneyWell STD725 is a high-performance differential pressure transmitter using advanced sensor technology. The STD725 provides extremely high measurement accuracy and stability over a wide range of static pressures and temperatures by combining differential pressure with static pressure and temperature compensation on the sensor chip. SmartLine is fully tested and experion@PKS compliant, providing the highest level of compatibility assurance and integration capabilities. SmartLine products can easily meet the most demanding requirements of pressure measurement applications.
