Modular temperature sensing apparatus

摘要

A temperature sensing device (30) includes a temperature sensor (36) in a sensor position within a sensor receiving opening (42) in an elongated sheath (32). An elongated sensor positioning member (38) and a sensor securing arrangement (50) work in unison to releasably fix the temperature sensor (36) in the sensor position at a closed end of the elongated sheath (32). An attachment structure attaches the elongated sheath (32) to a structure (29) such that a closed end (46) of the sheath extends into a medium to be sensed. Preferably, the securing arrangement (50) includes a lug (54) extending from the elongated sheath (32) at an open end (44) of the sheath. An attachment piece (58), slidably attached to the elongated sensor positioning member (38) engages the lug (54) and a biasing spring (60) biases the elongated sensor positioning member (38) away an end of the sensor positioning member (38) opposite the end upon which the attachment piece (58) is mounted so as to force the temperature sensor (36) against the closed end (46) of the elongated sheath (32).
