Active Sensors design and manufacture a wide range of rotary and linear position sensors for motion control and measurement systems. We specialise in contactless and potentiometer technology to produce sensor specifications to the highest quality and performance standards. The success we have achieved stems from an innovative and creative approach to precision engineering. This focused approach has made us the number one choice for control engineers worldwide.
CLS linear potentiometers are designed for the most demanding control and measurement systems. Available with a choice of mounting options and measurement ranges up to 1000mm (40"). A hardwearing electrical track provides long life and excellent resistance to vibration and shock.
RP rotary potentiometers are designed for the most demanding control and measurement systems. Used extensively in motorsport for throttle and gearbox control, steering angle measurement and the monitoring systems of the chassis. The RP is available with a choice of electrical angles and mounting options.
AC LVDT sensors for industrial, automotive and aerospace control and measurement systems. Advanced manufacturing techniques ensure superior sensor stablity, accuracy and repeatability in the most hostile of environments up to 200°C (400°F). Measurement ranges from 1mm to 200mm (8")
The RVDT is a contactless angular position sensor manufactured to quality standards required for high performance, high cyclic control and measurement systems. Available with measurement angles up to +/- 80° in single and duplex designs and is primarily used in aerospace applications.
Hall Effect linear sensors are designed to provide cost effective position measurement utilising proven contactless Hall Effect technology. They operate from a 5Vdc or 6-30Vdc supply and have an analogue output of 0.5V to 4.5V.
RH long life rotary position sensors are available with single, or dual outputs and up to 360° of electrical angle. Output options are analogue 0-5V. They have a 12-bit resolution (0.08°) over the measuring angle and an impressive update time of <2mS, making them ideal for dynamic control and measurement systems.
XLT (DC/DC LVDT - Linear Variable Displacement Transducer) sensors operate from a 5Vdc or 6 to 30Vdc supply with an output of 0.5 to 4.5V over a measurement range up to 200mm (8"). Precision wound inductive coils enable an improved temperature performance, low thermal drift, typically <+0.005%FS/°C compared to similar inductive sensors.
The XRT (DC RVIT) is housed in a stainless steel body and has measurement angles from 10° to 120°. The manufacturing techniques employed enables the necessary environmental protection required to provide a stable electrical output under vibration, acceleration, mechanical and thermal shock.
The PLS is a technology first 'contactless' ultra-slim linear position sensor with built-in electronics that works as simply as a linear potentiometer. The PLS is ideal for projects needing a competitively priced, accurate and reliable 'contactless' linear measurement device. The sensor dispenses with the need for costly and complex additional signal conditioning circuits.
The XCT in-cylinder sensor provides reliable position feedback for cylinder rods in hydaulic and pneumatic actuators. It is a robust, contactless sensor with integral electronics. The sensor has measurement ranges up to 300mm (12") and operates from a 5Vdc or 6 to 30Vdc supply.
For applications that do not permit the use of contactless sensors with integral electronics, which are usually mounting space restrictions or a high temperature environment, we offer the SCU3100 signal-conditioning unit. The unit is designed to operate remotely from the LVDT or RVDT sensor.
Most motor sport applications use speed sensors within the electrical system to accurately measure wheel, gear-tooth, camshaft and crankshaft speed. Hall Effect speed sensors require no magnets in the target as a magnet inside the sensor body creates the detection field, integral circuitry is then able to detect field changes as the target goes past.
