Lyophilizer and Deep-Freezer RTD sensors are designed to withstand the low-temperature vacuum of lyophilizers during their dehydration process. The RTD sensor measures temperatures between -100 to 200°C. The teflon coating of this RTD protects it from the hostile environment of the lyophilizers and deep freezers. Its teflon-insulated cable is rated for a maximum temperature of 250 °C and terminated into fork-type lugs. Other cable terminations can also be made, on request. Its 3-wire Pt100 RTD element can be constructed in single or dual assembly in Class A as per the IEC 751 standard for RTD sensors.
