WZP series explosion-proof platinum resistorDetailed product description：

Introduction to WZP series explosion-proof platinum resistors:

In chemical plants and production sites, various flammable and explosive chemical gases and vapors are often present. Using ordinary platinum resistors is very unsafe and can easily cause environmental gas explosions. Therefore, in these situations, explosion-proof thermal resistors must be used as temperature sensors. This explosion-proof platinum resistor product is suitable for use in places with explosive gas hazards within the temperature range of dIIBT4 to dIICT6.

Main technical indicators

model	graduation mark	Temperature measurement range ℃	Precision Level	Allowable deviation Δ t ℃
WZP WZP2 WZPK WZPK2	Pt100	-200～500	A-level	Allowable deviation when ± ＜ 650 ℃ ±(0.15+0.002ㄧtㄧ)
			Grade B	-Allowable deviation at 200-800 ℃ ± (0.30+0.005- t)

Note: "t" is the absolute value of the measured temperature of the temperature sensing element, and the dual platinum resistance is only supplied to Class B.
