Solinst Model 301 Water Level Temperature Sensor
- Absolute or Vented Pressure Sensor
- Easy Integration Modbus and SDI-12 for easy integration with Scada or PLC systems
- Available in Six Pressure Ranges 5m , 10 m, 20 m, 30 m, 100 m and 200 m
Overview
The Solinst Model 301 Water Level Temperature Sensor is a compact and versatile hydrostatic level transmitter that delivers precise and continuous water level and temperature measurements. Housed in a slim, durable 316L stainless steel casing (22 mm x 192 mm or 7/8" x 7.55"), this all-in-one submersible sensor is equipped with a water level pressure sensor and a temperature sensor.
To ensure reliable performance, the sensor features double O-ring seals that prevent leaks and a Faraday cage design that protects against power surges and lightning. The probe includes a removable nose cone for optional use of the 1/4" NPTM threaded connection. The water level pressure sensor offers exceptional accuracy of 0.05% FS, with readings automatically compensated for temperature variations.
Users can select from six pressure ranges (5-200 m) and choose between absolute and gauged (vented) pressure sensor configurations, tailoring the sensor to specific project requirements. The 301 Water Level Temperature Sensor is compatible with digital protocols such as Modbus and SDI-12, making integration into existing SCADA or PLC systems seamless.
