Sensors & Interfaces

We offer a comprehensive range of sensors to complement our data acquisition systems...

Key Features
Recorded/ displayed values are the true average value for the sampled period - there is zero sampling error Inherently eliminate potential for aliasing errors Enables slow recording rates for high frequency inputs without loss of information - e.g. Suspension movement, which has a typical frequency response of 1-2 kHz, can be recorded at 10Hz for measuring pitch and roll Up to 15 bit resolution (0.003%) and <0.5% total error over the whole operating range of a sensor

Stack provide a wide range of sensors and specialist interfaces to meet the vast majority of test and engineering requirements. We only offer sensors that have passed our rigorous testing program, and have proven suitable for test and engineering Applications.

Details of our main sensor types have been listed below:

Solid-state 0-5 Volt Output Sensors

These sensors typically offer 1% accuracy - over their whole operating range - and are ideal for monitoring chassis and engine parameters where Digital Signal Processing is not required.

The range of sensors includes:

0-3bar/50PSI, 0-10bar/150PSI Pressure Senors
0-100bar/1500PSI Pressure Sensors
-30°C to 150°C Temperature Sensors
50mm to 200mm Linear Displacement Sensors
10"/250mm to 20"/500mm String Potentiometers
+/- 5g Accelerometer with 5th order Butterworth low pass filter
120°, 360° Rotary Throttle & Steering Position Sensors

Digital Sensors and Interfaces

We manufacture our own range of high precision digital sensors and amplifiers incorporating Digital Signal Processing (DSP) within the sensor.

Used in conjunction with the ST8900 systems these sensors offer unrivalled performance, with up to 15 bit resolution (0.003%) and <0.5% total error over the whole operating range of the sensor.

Furthermore these devices also enable high frequency signals -e.g. 1-2kHz - to be recorded at any sampling frequency down to 1Hz without risk of aliasing errors, and can greatly increase the recording time of the data logging system.

The range of sensors and amplifiers includes:

5mV to 20V differential input amplifiers
K-Type Thermocouple Interface
Absolute Pressure Sensors
2"/50mm to 8"/200mm Linear Displacement Transducers
10"/250mm to 20"/500mm 'String Pot' Transducers
0.35 bar differential pressure sensor

Resistive Sensors

We also supply a range of automotive spec. pressure, temperature and rotary displacement sensors suitable for measuring basic engine condition and driver inputs.

The range of sensors includes:

0-2bar, 0-10 bar Pressure Sensors
-20 to 30 deg C, 0 to 150 deg C Temperature Sensors
120 degree, 360 degree Rotary Throttle & Steering Position Sensors
