Class A PT100 Temperature Sensor Transmitter 24V DC 4-20mA -50C to 250C
Product Description

An RTD Temperature Sensor Transmitter (Resistance Temperature Detector or Resistance Temperature Device) is one of the most prevalent temperature sensors used in industry today. Also commonly referred to as PT100/PT1000, its resulting popularity is due to its accuracy and repsonse, at temperatures between -300 to + 600 ° C.

Industrial thermal resistance is used as a temperature measuring sensor. It is usually used with instruments, recorders, and electronic regulators. It can directly measure or control liquid, vapor and gaseous media and solids, in various production processes from -200 °C to 600 °C. The temperature of the surface.According to the national regulations, our company’s fabricated thermocouples, meet the IEC international standard graduation number Pt100 platinum thermal resistance, and the professional standard graduation number Cu50 copper thermal resistance, two types of assembly, unified design type thermal resistance.

Temperature Sensor Transmitter

Application: Usually used in conjunction with display instruments, recording instruments, electronic computers, etc. Direct measurement of liquid, steam and gaseous media and solid surface measurement in the range of -200~500 °C in various production processes.
Measurement range
Accuracy level
Class A (±0.15°C+0.005|t|), Class B (±(0.30°C+0.005|t|)
Protection tube diameter
Φ12 (special outer diameter please specify)
Protection tube material
stainless steel 304,321,316
Thermal resistance wiring
two-wire wiring, three-wire wiring, four-wire wiring.
Thermal response time
T0.5 ≤ 45S (when the temperature changes stepwise, the output of the thermal resistance changes to 50% of the change, and thetime required is called thermal response time, expressed by T0.5).
Thermal resistance Nominal pressure
generally refers to the static external pressure, that can be withstood by the protective tube at room temperature withoutbreaking.
The minimum insertion depth of the thermal resistance
it should be no less than 8-10 times of the outer diameter of theprotection tube (except for special products).
Thermal resistance self-heating effect
When measuring the current 5mA through the thermal resistance, the measured resistance increment is converted into a temperature value of not more than 0.30 °C.
Thermal resistance insulation resistance
The test voltage of the normal temperature insulation resistance can be any valueof DC 10~100V, the ambient temperature is in the range of 15~35°C, and the relative humidity should be no more than 80%.The insulation resistance value at room temperature should be not less than 100MΩ.
