Autoclave Temperature Sensors

Our Autoclave RTDs are completely sealed. As a result, the entire sensor assembly of the Thermometrics, Autoclave RTD, including the probe and cables extending from the RTD, can be completely submerged in water without affecting accuracy or long-term stability.

Autoclave Sensors are designed for use in sterilization systems which require accurate temperature measurement.

There are three basic autoclave cycles;

1. Gravity or "Fast Exhaust" cycle - For dry goods, glassware, etc. This cycle charges the chamber with steam and holds it at a set temperature for a set period of time. At the end of the cycle a valve opens and the chamber rapidly returns to atmospheric pressure. Drying time may also be added to the end of the cycle.

2. Liquid or "Slow exhaust" cycle - Used to prevent sterilized liquids from boiling, steam is exhausted slowly at the end of the cycle, allowing the liquids (which will be super-heated) to cool.

3. Pre-Vacuum cycle - For porous materials, animal bedding, etc. This cycle partially evacuates the chamber prior to introducing steam for greater steam penetration. Pre-vacuum cycles are not available on all machines.

Sanitary Flanged SensorsSanitary Flanged Sensors
Our autoclave sensors have a temperature range of –100 to 200ºC and are sealed for severe steam service. The sensor accuracy at 121ºC is ± 0.3ºC and is available as a Pt 100 ohm, 0.125” O.D. high polish sheath x 5” long with 60” of lead wire.
Global Reach
Instrumentation Wire and CableInstrumentation Wire and Cable
RTD & Thermocouple cable are available with a variety of insulations &temperature ranges for use in Autoclave applications. 20 AWG wire with TFE Teflon Fused Tape insulation has a range to 260°C. This is used to prevent moisture migration thru the wire when steam seal is critical.
