Thermistors, Probes, PTC and NTC temperature sensors for military and commercial applications, by Quality Thermistor Inc.

Introducing a new high-temperature NTC thermistor part suitable for continuous operation up to 300°C. The hermetic QTGBHT series can also be used in high humidity, and even in full liquid immersion applications. The small, .085" (2.16mm) glass bead provides for excellent thermal time response and offers very high stability. For high temperature applications where solder attachment of lead wire extensions is not feasible, the QTGBHT is ideal with #36 awg, Platinum clad, Nickel/Iron alloy leads, suitable for welding lead wire extensions. A high Alpha value NTC material has been used to achieve high resolution at the extreme temperatures at which the part is designed to operate.

The QTGBHT series now gives the design engineer a cost effective, high performance alternative to Platinum based temperature sensors, and can provide for a more accurate and easier to interface temperature sensor than a thermocouple.
