Explosion proof industrial thermistor

Explosion proof industrial thermistor

OverviewWZ □ - □ 4 □ Explosion proof industrial thermistor is designed and manufactured in accordance with the mandatory national explosion-proof standards GB3836.1-2000 and GB3836.2-2000, and has been inspected and approved by the national level instrument explosion-proof safety supervision and inspection station, and has obtained an explosion-proof certificate. It is suitable for use in explosive gas mixture environments under specified conditions.
Explosion proof grade: dIIBT1~6
Explosion proof certificate: GYB13.1609X
Execution standard: GB3836.1-2000 General requirements for electrical equipment used in explosive gas environments
GB3836.2-2000 Electrical equipment for explosive gas environments - Explosion proof type "d"
JB5518 "Technical Conditions for Industrial Thermocouples and Thermal Barrier Explosion"
Standard structural formWZ □ - □ 4 □ Explosion proof industrial thermistor is a temperature sensor composed of a flameproof junction box, a thermistor temperature sensing element, and an external protective tube with threaded or flanged installation and fixing devices. It can be widely used for temperature measurement in the range of -200~420 ℃ in the dIIBT1~6 temperature group area with explosive gas hazards.

Model specifications

Note: 1. When placing an order, please indicate the model, division number (Pt10, Pt100, Pt1000, Cu50), tolerance (accuracy) level (if not specified, platinum resistance thermometer provides B-level accuracy), size of the fixing device thread or flange, diameter of the protective tube, nominal total length L (L=l+150), protective tube material, compression nut (if not specified, 1Cr18Ni9Ti is provided), and quantity.
2. Please indicate the usage conditions as much as possible when placing an order, such as temperature, measuring medium, and pressure, so that we can recommend an economical and reasonable optimization plan.
