P855 Pressure Transducers with Serial(485) Interface
- RS485 Serial interface for digital operation
- Digitally compensated for high accuracy
- Excellent stability over wide thermal range
- 0.1% Full scale accuracy, 0.25% Max temperature error
- Zero, Span set by switches – No potentiometers
- For liquid or gas service
- Full scale ranges from 2.22 inH2O
- NEMA 4 Housing
The P855 Serial Pressure Transducer is Ideal for:
- Flow Measurements
- Level Measurements
- Hydraulic Systems
- Vehicle Testing
The Validyne model P855 serial pressure transducer allows for a RS485 digital interface to read pressure, calibration date, and unit information. It also outputs in voltage for an analog output. The zero and span can be set using the communication protocol.
The P855 serial pressure transducer is designed for a wide variety of low pressure measurements where fast dynamic response, high resistance to vibration and superior signal stability through temperature change is required. The P855 will accept both liquids and gases directly at the sensing diaphragm.
The zero and full-scale outputs are set by switch. No potentiometer adjustments are required to calibrate. A second switch provides 2.5x gain change and this smaller range may be offset to any place within the full range.
The P855 has 1/8 inch female NPT pressure connections and measures just 1.5 x 1.5 x 5 inches overall.
The P855 is available in +/-5 VDC output with a RS485 connection.
Wiring options for the P855 include a six-pin PT02A connector and pigtail leads. A 1/2 inch male NPT conduit thread connection for mounting a junction box is included with the pigtail lead option.
