Pure Nickel Nickel 270 Nickel Iron RESISTORS wCAPS & COILS wDELAY LINES High temperature RTD (Resistance Temperature Detector) elements are designed for the toughest industrial applications. PTC sensors feature an all-welded construction for increased durability under stress and vibration. Wirewound element results in exceptional stability and uniformity. Series PTC elements can be used to sense or regulate air environments and can be assembled into immersion probes for liquid environments (refer to PTS Series). d Temperature Max.

Typical time constant for PTC 150 PT 100 ohm is 2.2 seconds in water moving 3ft./sec. Consult factory for particular specifications. SELF-HEATING is contingent upon resistance value, alloy, and element size. Typical self-heating for PTC 150 PT 100 ohm is 65 mW/C in water moving at 3ft./sec. Consult factory for particular specifications. INTERCHANGEABILITY - The strain-free design of RCD sensors insures maximum repeatability. This characteristic is degraded by lot-to-lot inconsistencies of the various wire alloys. Platinum being extremely consistant allows the best interchangeability characteristics. Consult factory for specific data based on particular alloy and tolerance. 1.0 SHOCK AND VIBRATION - PTC elements withstand 100 G's sinewave shock for 3 cycles at 10 milliseconds, and withstand vibration 10Hz to 2200Hz at 20 G's. 0 0 32 100 212 200 300 400 392 572 752 500 600 932 1112 C TEMPERATURE F P/N DESIGNATION: RTD PROBES TEMPERATURE RATING UP TO 500C 2655-41-5 a OPTIONAL PTC150PT - 1000 - F B 392 RCD Type 4-Digit Resis.

These probes (PTS Series) are moistureproof and pressure tight and in many instances may be directly inserted into process lines or thermowells for precise temperature readings. Series PTS are available in any standard PTC resistance value and temperature coefficient, in .125 [3.18], .187 [4.75], .250 [6.35] diameters. Teflon insulated leads are standard. Other insulations available for highest temperature requirements, 3-terminal, 4terminal configurations available. Probe lengths available from 0.5 [12.7] to 18 [457].
