   Holder, and Probe

The CMCP1210 series bearing temperature sensor provides, fast and accurate readings from bearings, blocks, and other solids. The spring-loaded holder ensures solid contact in drilled holes with a built-in oil seal. The sensing probe features a copper alloy tip for quick response to temperature changes. Probes may be cut to length in the field using a tube cutter.

Spring-loaded holders provide a quick and simple installation of probe sensors pull out and twist the knob, insert the probe until it bottoms out, and release the knob. Spring pressure holds the probe tip in contact with the measuring surface for faster response and more reliable measurements. Features a rubber O-ring that doesn't crimp the probe but prevents oil leakage to 50 psi (3.4 bar) at up to 260°C.

1. Holder is equipped with a double containment system which has two O-ring seals that seal around the probe. If the first O-ring is breached, the fitting will leak via the weep hole. The second O-ring will keep measured medium frmo reaching electrical components.
2. O-ring material: Viton
3. Temperature limit: 260°C (500°F) maximum.
4. Pressure: Holder will withstand 50 PSIG at maximum temperature without any leaks around the O-ring seal.

1. Element: Platinum
2. Temperature limits: -50°C to 260°C (-58°F to 500°F)
3. Insulation resistance: 1000 MEGOHMS minimum at 500 volts DC, leads to probe case. Dual element only: 100 MEGOHMS at 100 volts DC, between elements.
4. Leads: AWG #26, stranded, TFE insulated.
5. Case: Stainless steel, with copper alloy tip.
6. 0.236 ±.005 [6.00 ±0.13] for this length only.
7. The PD and PA resistance thermometers will meet the resistance-temperature relationship and tolerances specified in IEC 751, Class B.
8. Probe is suitable for use in harardous locations defined by CENELEC EN 50 014 and EN50 018, EEx d IIC T6.

1. The assembly is suitable for use in hazardous locations defined as follows:
