    How (MEMS) Oil-filled-pressure-sensor Work

    In MEMS sensor technology, the pressure of the media is measured by a silicon or silicon-on-insulator sensing element that has the piezoresistive strain gage bridge on it, with a transfer medium, typically silicon oil, present between the MEMS element and a stainless-steel diaphragm.

    Thin Film Sensors and Transducers

    Thin film sensors are more robust and less complex than MEMS sensors. Their simple structure makes them easier to manufacture at a lower cost and they provide incredible accuracy and reliability even in harsh operating conditions such as extreme temperatures (less than -40℃ and as high as +150℃).

    Applications of Absolute Pressure Sensors

    With the rise in smart watches and navigation systems, absolute pressure sensors find homes wherever elevation above sea level (altimeter measurement) is required. Weather stations also use them for barometric pressure measurements.

    Force Torque Sensor (FT Sensor) Six-axis sensors

    The most popular type of force torque sensor is the six-axis sensor. This particular force torque (FT) sensor is capable of measuring forces in every direction. A six-axis FT sensor generally utilizes strain gauge technology; when pressure is applied, the resistance within the gauge increases or decreases proportionally to the force it receives. This is how the sensor measures the movement of its external frames in relation to one another. Six-axis sensors can be found in robotic arms at the “joint.”

    How accurate is a RTD sensor (Pt100) classes A, B

    How accurate is a RTD sensor (Pt100) classes A, B In China's national standard, PT100 has two accuracy classes: Class A and class B Measuring Range:-200℃~+850℃Class A accuracy(0.15+0.002*|t|)℃;Class B accuracy(0.30+0.005*|t|)℃; Note: |t| is the absolute value of actual temperature.

    Temperature Transmitters, temperature sensors,RTD, PT100

    A temperature transmitter is a device that connects to a temperature sensor to transmit the signal elsewhere for monitoring and control purposes. Typically, the temperature sensor is either an RTD(PT100 or PT1000), thermistor or thermocouple type sensor and will interface with a PLC, DCS, data logger or display hardware. The temperature transmitter's role is to isolate the temperature signal, filter any EMC noise, amplify and convert the temperature sensor's signal to a 4-20mA or 0-10V DC range for further use.

    How to use pressure sensors for harsh environments

    Physical separation from hazardous media: Fluid-isolation barrier can be implemented to prevent corrosive media coming into direct contact with the sensor diaphragm; Heat is dissipated from the media in the tube.

    Pressure sensors for corrosive media

    Pressure sensors for use with corrosive media often feature housings made from stainless steel or plastics such as PVDF, PVC or PPS. TM Sensor use a stainless steel diaphragm backed by silicon oil that transfers pressure to the sensing element.
