Water Level Temperature Sensor, Full Scale 20m (65.6ft), Absolute Pressure Sensor
Water Level Temperature Sensor The Water Level Temperature Sensor is a compact, allin-one submersible hydrostatic level transmitter that provides continuous, stable and accurate water level and temperature readings for a wide variety of applications. The water level pressure sensor and temperature sensor are enclosed in a slim, robust 22 mm x 192 mm (7/8" x 7.55") 316L stainless steel housing. Double o-ring seals prevent leaks and a Faraday cage design protects against power surges and lightning. Each probe features a removable nose cone for optional use of the 1/4" NPTM threaded connection. The durable water level pressure sensor provides 0.05% FS accuracy with automatically temperature compensated readings. There are six pressure ranges to choose from (5-200 m), with options absolute pressure sensor setups. Communication cable assemblies are available in lengths up to 300 metres. The cables are easily and securely attached to the sensor using a threaded connection. Simple PC software utilities are used to set up the sensor for the different protocols, perform simple diagnostics, and update sensor firmware if required. A USB-A programming cable is provided for connection to the PC.
