STD800 series differential pressure transmitters are designed around high-performance piezoresistive sensors.By combining differential pressure sensing with static pressure and temperature compensation on the chip, high precision and stability are provided
Original imported Honeywell differential pressure transmitter STD820-STD820-E1HC4AS-1-0-AHB-11S-A-10A0-F1
All ST 800 transmitters are modular in design, supporting the user's ability to change instrument bodies, add indicators, or change electronic modules without affecting overall performance or approval authority certifications. The STD800 model is available with a variety of calibration options.In lieu of standard factory calibration, the unit may provide 1,2, or 3 customer specified calibrations.
