Absolute range level sensors for measuring liquid level where it is not possible or practical to provide a vented gauge reference.
Economical IP68 protected sensor with stainless steel 316L housing and Ceramic strain gauge sensing diaphragm for measuring liquid depth pressure or the pressure in a submerged pipe or vessel. Measure hydrostatic pressure from from 0 to 10 mWC (33 ftWC) up to 0 to 100 mWC (330 ftWc) and convert reading to a millivolt, current or voltage signal output. The Ceramic diaphragm has a high chemical resistance to media such as leachate and seawater, and the housing can be upgraded to Duplex stainless steel if necessary for extra material protection. A PUR coated cable is fitted as standard, but for additional chemical protection an FEP coated cable can be supplied.
Absolute referenced hydrostatic depth sensor with an IP68 sealed electrical interface, stainless steel 316L, Duplex or PVC housing and a mV, amplified voltage or current output. Available in depth ranges from 1 to 10 bar absolute.
IP68 combined liquid level and temperature, dual 4 to 20 milliamp output pressure sensor with a 316L or Duplex stainless steel housing and a high corrosion resistant ceramic sensing diaphragm. The IMCTL is available with ranges starting from 10 mWC (33 ftWC) to a maximum range of 100 mWC (330 ftWc) and can measure temperature over a choice of four different scaled ranges between -20 to +60 degC.
Water resistant pressure sensor for measuring hydrostatic pressures in the range of 0-0.5 mWC up to 0-100 mWC. An all stainless steel 316L construction with Viton O rings seals and a choice of PUR, PVC or FEP vented cabling. The IMSL is used for measuring groundwater, aquifer, reservoir and borehole water level. The internal silicon strain gauge sensor provides a stable water level reading accurate to 0.1% of span linearity with low hysteresis and repeatability errors.
Stainless steel 316L waterproof probe for measuring both water temperature and depth and generating two separate 4-20mA current loop measurement signals. Select temperature measurement ranges from -20 to +60 deg C and depth ranges of 0-0.5mWG to 0-100mWG.
IP68 protect pressure sensor for monitoring fresh water level to depths of 100 metres. This stainless steel drinking water compatible level sensor has been assesed and certified by the Water Regulations Advisory Scheme (WRAS) for compliance with the UK water regulations. The materials and fittings used in the mechanical construction of the IWSL water level sensor meet the standards required by the water supply byelaws of England, Wales and Scotland.
Marine approved level transmitter with 4-20mA current loop output for measuring the level of contents inside a ships ballast, fuel, liquid cargo or wastewater tanks with optional all CuNiFe construction for sea-water compatibility in ranges from 0.4 mH2O to 200mH2O gauge or absolute.
SDI-12 protocol transducer for sensing water depth level and temperature in seawater, brackish water, tidal water, saline water or leachate. The digital interface conforms to the requirements of the SDI12 support group and can be used with environment monitoring equipment which supports the SDI12 digital communications interface. A high corrosion resistant ceramic diaphragm is fitted a standard and stainless steel 316L, Duplex or Marine Bronze housing materials can be chosen to suit the application requirements. Measure salt water depth in the ranges starting from 0-10 metres up to 0-100 metres, including absolute non-vented ranges from 1.5 bar up to 10 bar absolute.
Combined pressure and temperature sensor with a 1200 baud rate serial data interface as defined by the SDI-12 support group. The S12S is a submersible probe used for monitoring water level and temperature. The SDI-12 digital interface is specially designed for low power, battery operated instrumentation such as on-site environmental dataloggers. Measure the rise and fall of water levels in ranges from 0 to 2 feet up to 0 to 300 feet of water column.
Analogue output sensor for immersing in seawater to determine depth or change in water level by measuring hydrostatic pressure. This sea depth probe has a Marine bronze housing and Ceramic diaphragm for protection from saltwater corrosion. Select fixed ranges from 10 metres (33 feet) up to 100 metres (328 feet) depth in a number of analogue output configurations including low voltage strain gauge, amplified voltage and current loop output. Also suitable for use in brackish and inland tidal water or any other application where there is the risk of corrosion form a saline liquid.
