For over 40 years Sensor Technology has researched and developed solutions for customers' measurement requirements, creating its own unique technologies for the instrumentation, test and OEM markets worldwide and supported by a global network of distributors.
The industrial division manufactures the TorqSense and LoadSense ranges of rotary torque and wireless load transducers, offering accurate, affordable, market leading products across the whole range of industrial applications. The avionics division manufactures the HeliNav LoadMaster, which provides an accurate measurement of underslung loads for the helicopter industry.
TorqSense Rotary Torque Transducers
TorqSense Digital torque transducers offer cost effective, non-contact digital rotary torque measurement, using Surface Acoustic Wave (SAW) technology, suitable for torque monitoring, testing or controlling drive mechanisms. TorqSense transducers and their technology are particularly appropriate for OEM applications.
TorqSense RWT410/420 series features integral digital electronics with low power consumption of 3 watts, high frequency response, resolution of 0.02% of FSD and increased transducer overload to 300% and ranged available from 1Nm to 13000KNm.
Other ranges of TorqSense RWT transducers available include the RWT430/440, with a smaller sensor head and separate electronics module, and the RWT450/460 pulley/sprocket torque sensors, designed to be a direct replacement for a standard pulley/sprocket.
The ORT230/240 series of Optical Rotary Torque Sensors range from 10mNm to 100Nm with speeds up to 30,000rpm. They feature low torque ranges, low inertia and high bandwidth.
The latest version of TorqView software has been written in NI LabVIEW, to provide a very simple yet user-friendly measurement analysis and data presentation interface. However, single VI's are available for users with LabVIEW.
LoadSense Wireless Load Sensors
The wireless LoadSense load sensor is a strain gauge based stainless steel tension type sensor with the capability of wirelessly transmitting its data to one of our compatible readouts and displays or recording its data locally. Its inbuilt 32MB memory can hold up to 149 hours of data, which can then be downloaded to a PC via its USB cable. The Load Sensor transmits using the worldwide licence free frequency of 2.4GHz on two built in antennas.
The new development allows weighing processes to be fully integrated with handling operations. All live data is captured in real time and can be transferred to a database, stored, totalised and analysed. The load sensor can be integrated with a crane hook, fork lift or other handling device.
The LoadSense load sensors – sizes from 1 Tonne to 50 Tonnes, can be used with our Handheld Receiver Display or Cabin Receiver Display which can read several devices at the same time, and/or our standalone Receiver Interface which is used to output the data via RS232/RS422 to a PC.
LoadView Virtual Instrumentation Display Software is available to provide the user with a very cost-effective solution to measuring, recording and displaying data from one or more load sensors.
Wireless Strain Gauge Transmitters
The WSG series of wireless strain gauge transmitters offers the ability to convert any strain gauge based sensor into a wireless one. Using the same 2.4GHz technology as the LoadSense series, data can be transmitted over 100m to one of our readouts/interfaces. Modules include DIN rail type and can also come with various battery options.
HeliNav LoadMaster Helicopter Load Monitoring
HeliNav LoadMaster is an intelligent wireless helicopter load sensor with inclinometer and accelerometer capabilities so that it can be used with large underslung loads. It is available in a range of sizes from 1 tonne to 10 tonnes. The HeliNav LoadMaster sensor is completely autonomous and can also interface to its own receiver/display mountable in the cockpit. This makes it independent of the host helicopter’s systems, while being wireless means it does not require additional certification of the electrical systems. It also means it can be swapped from one craft to another in seconds, allowing HeliNav LoadMaster to be shared around a fleet of aircraft. A handheld receiver/display, able to interrogate several different LoadMaster sensors, is also available for ground crew use.
