What is a sensor?
A sensor measures a physical quantity. The variables are located in the following areas: pressure, force, inclination, displacement, acceleration, temperature, strain, vibration or any one of a great number of other environmental phenomena. Sensors convert the measured quantity into a standardized control signal that is converted to a human-readable display at the sensor location or transmitted electronically over a network for reading or further processing.
Pressure Sensors measure absolute, gauge and differential pressures. The sensors are based on the latest piëzoresistive foil strain-gauges and inductive measuring methods.
Force Sensors convert a force into a linear electrical signal. Their operation relies on measuring miniature movements in a precision metal structure using foil strain gauges. Measurement ranges: 0.5N to 1,500kN.
Load cells and Weighing Sensors convert a load or force into an electronic output. Weighing sensors can be either compression or tension based or bi-directional. Measurement ranges from 0.25 kg to 250 tonnes.
Worldwide you will find our Dynamic and Static Torque Sensors in applications for marine, offshore, automotive, aerospace and energy. Ranges from 0.01 Nm up to 10kNm.
Strain Sensors are developed to measure strain on an object. The straingauges are made of electrical wire or photo edged foil resistance material. Measurement ranges from ±500 μe to ± 5,000 μe.
Linear Position Sensors convert displacement of an object into an output signal and are perfectly suited to perform accurate and reliable measurements. Measurement ranges from 0.125 mm to 600 mm.
Laser Position Sensors are high speed, high resolution and very accurate sensors for displacement and position measurement in harsh environments. Measurement ranges from 0.125 mm to 600 mm.
Rotary Position Sensors are suited for precise angle measurement. The magneto resistive rotational speed sensors are compact and easy to design in. Measurement ranges: 0.125 mm to 600 mm.
Tilt & Inclination Sensors measure the angle or position of an object in relation to the earth's gravity. Measurement ranges from 1° to 360°, analog & digital interface.
Acceleration Sensors are used to measure vibration, shock, displacement, velocity, inclination and tilt in high accuracy applications. Frequency response up to 7000Hz. Range from ±1g up to ±6000g. Operating temperature from -40C° up to 125C°.
Vibration Sensors are piezoelectric accelerometers that sense vibration. They are used for measuring fluctuating accelerations or speeds or for normal vibration measurement. Frequency range from 0.2 up to 2500 Hz.
Gyroscope Sensors are used whenever rate of turn sensing is required without a fixed point of reference. The gyroscopes incorporate the latest silicon MEMS sensors and contain either analog or digital output. Range from -75°/s up to 2,700°/s.
Conventional electronic sensors frequently come up against the limits of technology because interfering effects such as high voltages or EMI limit the operability of the systems. In these environments our Fiber Optic Sensors can create new possibilities for reliable measurements.
Temperature Sensors are used to accurately measure temperature from a distance by detecting the infrared radiation of an object. Temperature sensors are used for applications such as driers, ovens, metal and glass industries or semiconductor production.
