    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.

    Piezoelectric pressure sensors

    The main advantages of piezoelectric sensors are robustness and low power. The sensing elements are made of rigid materials, which can be natural crystals such as quartz or specially formulated ceramics. These require only a very small deformation to generate an output, so there are effectively no moving parts.

    Advantages and disadvantages of Capacitive sensors

    The capacitive element is mechanically simple and robust. Capacitive sensors are able to operate over a wide temperature range and are very tolerant of short-term overpressure conditions. They can be used to measure a wide range of pressure from vacuum (2.5 mbar or 250 Pa) to high pressures up to around 10,000 psi (70 MPa). They’re ideal for both lower-pressure applications and reasonably harsh environments.
