Geotechnical
 Pressure sensors & instrumentation for measuring and recording pressure and level on applications such as bore-hole, soil & concrete testing.
Product List
Level TROLL 500 Level Data Logger
Battery powered submersible data logger for recording level of rivers, reservoirs, boreholes, tidal & coastal waters with ranges from 3.5 mH2O up to 350 mH2O gauge or absolute
CNS Submersible Low Level Transmitter
Immersible low pressure sensor for measuring shallow liquid level with a rangeable 4-20mA current loop or high level voltage output signal in level ranges from 80mmH20 up to 160mH2O
Vantage Pro2 Wireless Weather Station
Weather station with complete suite of wireless solar powered sensors for wind speed, wind direction, relative humdity, dewpoint, inside/outside temperature and rainfall for meteorological measurements.
Baro TROLL Barometric Pressure Data Logger
Battery powered data logger for recording atmospheric pressure with an accuracy of ±0.1% full scale. A temperature sensor is also included with an accuracy of ±0.1 DegC.
Level Tape 100 for Calibrating Water Level Sensors
The level tape 100 system is used for determine the depth to water level and the bottom of the well graduated in metres by millimetres or feet by 0.01 feet. The reel unit produces an audible buzz when the probe hits the water and the tape goes slack when the probe reaches the bottom of the well.
Level Tape 200 for Measuring Water Depth
Level tape 200 system is used for manually measuring the water depth of a well or borehole or for calibrating the water level datum when installing a water level sensor. Manufactured and tested to ASME (American Society of Mechanical Engineers) requirements the water level tape 200 incorporates enhanced features such as heavy duty polyethylene jacketed tape with black print on yellow background for easy reading, sensitivity adjustment via touch pad control for filtering out false readings due to running water, tape tensile strength of 300lb and an included carrying bag
IML IP68 Millivolt Output Level Sensor
Hydrostatic level sensor with an IP68 sealed electrical connection, stainless steel 316L or Duplex construction and a passive millivolt strain gauge output signal. Available in level ranges from 5 to 200 mWG gauge or absolute.
IML Submersible Absolute Reference Depth Sensor
Absolute referenced hydrostatic depth sensor with an IP68 sealed electrical interface, stainless steel 316L or Duplex housing and a mV, amplified voltage or current output. Available in depth ranges from 5 to 200 mWG gauge or absolute.
KL1 Cable Junction Box for Submersible Level Transmitters
Robust cable junction box for terminating vented electrical cable from a 2 wire submersible hydrostatic level transmitter. The inside of the IP66 sealed box is vented to the ambient outside air via a PTFE filter to ensure the level sensor is properly vented to compensate for atmospheric pressure.
Level TROLL 700 Logarithmic Level Data Logger
Battery powered submersible data logger for recording level of rivers, reservoirs, boreholes, tidal & coastal waters with ranges from 3.5 mH2O up to 350 mH2O gauge with non-linear logging functions and extra memory capacity for recorded data.
LevelTROLL 300 Non-Vented Borehole Water Level Logger
The level troll 300 bore hole water level data logger is available in measuring ranges from 10.9 m up to 200.7 mH2O. To compensate for atmospheric pressure the device can be used in conjunction with the Barotroll atmospheric pressure logger or a known value can be entered into the software to adjust the readings.
LMK306 Ground Water Level Transmitter
IP68 sealed hydrostaic level transmitter with a 17.5 mm diameter for lowering into ground water boreholes for environmental monitoring of water level. Available in level ranges from 6 up to 200 metres of water gauge (650 ftH2O gage) with an accuracy of 0.25% full scale BSL.
LMK807 Plastic Submersible Level Transmitter
IP68 mid range pressure transmitter for measuring the level of highly contaminated and agressive liquid media with a body made from PVC or PVDF. Hydrostatic ranges from 4 mWC up to 100 mWC
LMK809 Plastic Submersible Low Level Transmitter
IP68 low range pressure transmitter for measuring the level of highly contaminated and agressive liquid media with a body made from PVC or PVDF. Hydrostatic level ranges from 0.4 up to 4 metres of water column.
LMP305 Borehole Level Transmitter
Submersible stainless steel pressure transmitter ideal for geotechnical surveying with a 19mm diameter for measuring hydrostatic water level in bore-holes. This small diameter level sensor has level ranges from 1 up to 250 metres water column and a 4-20mA current loop output signal.
LMP307 Submersible Level Transmitter
Submersible level transmitter for measuring liquid level with a 4-20mA current loop or a 0-10V voltage output plus optional ATEX approval for instrinsically safe use in hazardous areas in ranges from 1mH2O up to 250mH2O.
TPS Strain Gauge Pressure Sensor
Piezo-resistive pressure sensor with a millivolt output direct from a four arm wheatstone bridge strain gauge circuit in pressure ranges from 10 up to 1000 bar gauge.
TPSA Precision High Pressure Transducer
High pressure transducer for pressure testing applications with 4-20mA current loop or amplified voltage output signal available in pressure ranges from 50 up to 1000 bar gauge to with a measurement accuracy of 0.1%.
