    What is the difference between Rated Capacity Load, Maximum Load, and Safe Load Limit?

    The rated capacity is the maximum recommended load for a particular load cell. All load cells have a range of loads where the output signal is proportional to the load; that is the deformation of the strain gauge caused by the load produces an output signal having an approximately linear relationship to the strain. By keeping the rated capacity in this range, the strain gauge produces outputs within the errors printed on the accompanying load cell data sheet.

    Excitation Voltage of load cell

    Higher voltages through the resistive strain gauges (which comprise the Wheatstone bridge) will cause more current to flow and heat the strain gauges. The cell body acts as a heat sink to keep the gauges cool. If the maximum rated excitation voltage is exceeded, the heating will cause signal perturbation or gauge failure. Additionally, in battery operated devices, high excitation voltage (and thus, current) will cause the battery to deplete much faster than with lower excitation voltages through the circuit.

    Load Cell Installation

    Load cells have a specified load direction, do not apply side forces, bending or torsional movements on load cells. Inappropriate loading applications will risk reducing the life of load cells, plus distortion of correct measurement results.

    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.
