WZPK series armored thermal resistance

     Our platinum resistance components have smaller volume, long life, credible broad temperature range (common component -200℃-500℃; high temperature component -200℃-700℃[1-5mA]) and suitable for stronger checking current (1-3mA). It solves the users’ trouble that it is unreliable to measure over 300℃ temperature with high spontaneous heating with thin chip components. Not owing to unreliable platinum resistance components, change the temperature measurement system of platinum resistance components into the temperature measurement system of galvanic couple with low precision, bad antijamming capability. Reliability of our components is predominant and unique between 300℃ and 700℃. Further more, if not satisfy sealing by glue in the place of leading the armored cable lead, such as require too high for the lead life because of too high environmental temperature (≥150℃) or the leads in the too damp environment, sinter to sealed by ceramic glaze.
一、The specs of armored resistance wire(graduation Pt100)
-200℃-500℃         ∮3      ∮4     ∮5      ∮6      ∮8
(the length of single component and twin components<50M)
-200℃-800℃         ∮4      ∮5     ∮6      ∮8 
(the length of single component and twin components<50M)
(Our armored resistance wires are all aligned by straightener)
Explanatory notes for order: diameter, the general length of armored cable, materials (304、321 or 316L),temperature range, precision(Class A and B), three-wire or two-wire system, external lead is 60mm high temperature lead if no special notes
二、 Non standard armored thermal resistance
1.Platinum resistance with armored and long lead

Note: The type and length, armored resistance length L, thread position, armored diameter, temperature range and materials (304、321、316L) as the users’ indication.
    This type products replace entirely WZPK-173 WZPK-273 WZPK-473 WZPK-573 and adopt preliminary shaft technique which has much excellence such as the cable fixed hard, to be waterproof, dampproof, flameproof, without connector and avoid the error made by contact resistance, etc.
