The PT12 Pressure/Temperature Sensor has been designed to provide trouble-free submersible operation in liquid environments. This sensor communicates via SDI-12 (v1.3) or Modbus® RTU (RS485)protocol. Pressure/level is measured with an extremely rugged and stable piezo-electric, media isolated pressure element and compensated for temperature using our proprietary calibration methodology. Temperature is measured using an on-board digital chip.
This industry standard SDI-12 device is easy to interface with SDI-12 recorders and can be daisy-chained on one cable up to 200 feet, making it a preferred choice for many environmental professionals with existing SDI-12 systems.
Cable Type: polyethylene, polyurethane, or FEP
Cable Length: up to 500ft
Vented or Non-Vented Version ( Gauge/Absolute Pressure)
