    Digital Temperature Sensor with transmitter, Pt100, 2 Wire

    RTD sensor with digital meter can directly display high-precision real-time temperature. It converts temperature to 4-20mA standard signal proportional to the electrical signals of thermistor, and outputs to display instrument or DCS system in control room. Built-in small transmitter adopts silicone rubber seal structure, good anti-interference ability, shock and humidity, apply to harsh environments. Measuring temperature range -200~+420 ℃.

    RTD temperature sensor can directly provide accurate input signal of temperature changes for display instruments, recording instruments, signal conditioners, scanister and computer.


    1. RTD temperature range and accuracy chart

    Type of sensing element Measuring range Allowable deviation Δt
    Pt100 -200~420℃ Class B (-200~800℃) Permissible deviation ±(0.30+0.005|t|)
    Class A (-200~650℃) Permissible deviation ±(0.15+0.002|t|)
    Cu50 -100~150℃ -50~100℃ Permissible deviation ±(0.30+6.0*10-3t)

    Note: t is the actual measuring temperature absolute value of the temperature sensing element.
