Autoclave Resistance Thermometers - Pt100 Sensors

Autoclave Load RTD (Type 69A)

The harsh conditions found in the autoclave chambers of sterilisers require a reliable sensor, as all too often sensors can fail and instrumentation be damaged through ingress of moisture. These autoclave load sensors offer a reliable solution to the problem.

Available in tolerance classes B or A, they can be supplied as simplex or duplex assemblies in a 3-wire configuration and comprise of a stainless steel sensor tip, a length of Wire inside a flexible stainless steel conduit, a stainless steel feed-through and then flying leads oversheathed with silicone rubber.
