There is described a method of detecting failure in an array of thermocouples connected in parallel. The method comprising: during an operation mode of the array of thermocouples, measuring a voltage V across the array of thermocouples, the voltage V associated with a temperature T; during a failure detection mode of the array of thermocouples, shunting the array of thermocouples, and measuring a shunt voltage Vs occurring across a resistive element connected in series with the array of thermocouples; comparing the shunt voltage Vs to an expected shunt voltage Vs_exp for the array of thermocouples at the temperature T; and generating a failure signal indicative of a detected failure in the array of thermocouples when the shunt voltage Vs deviates from the expected shunt voltage Vs_exp by more than a deviation threshold.

An electronic device having at least one connector for at least one wired sensor. The device has a sensor break detection unit, wherein the sensor break detection unit comprises a pulse generator outputting pulses of different polarity being adapted to output at least one electrical signal to the wired sensor and detector means for detecting a response signal from the wired sensor.

A sliding bearing and a method for its manufacture are disclosed. The sliding bearing may include a metallic substrate, an electrically insulating layer on the metallic substrate, and an electrical component on the electrically insulating layer. The sliding bearing may be operatively connected to a monitoring module configured to monitor the electrical component.

Instead of a single-element sheathed thermocouple, a sheathed thermocouple is used in which: two pairs of thermocouple wires are enclosed in a metal sheath while being embedded in an inorganic insulating material powder, the thermocouple wires being made of the same materials as and having a diameter that is 90% or greater of or substantially equal to the diameter of thermocouple wires of the single-element sheathed thermocouple, and the metal sheath being made of the same material and having the same outer diameter and wall thickness as a metal sheath of the single-element sheathed thermocouple; only one pair of the two pairs of thermocouple wires are joined to each other at leading ends to form a measuring junction; and a base end of the metal sheath is sealed with a seal with the pair of thermocouple wires joined to each other at the leading ends passing therethrough.

A thermo wire testing circuit, comprising: a current source terminal for supplying a test current to a first thermo wire via a first terminal during a test mode; a current drain terminal for receiving the test current from a second thermo wire via a second terminal during the test mode; a reference resistor for generating a reference voltage, which reference resistor is arranged in the current circuit of the test current; and a processing unit coupleable to the first and second terminals and to the reference resistor, and configured to compare a voltage drop caused by said test current between the first and second terminal with the reference voltage.

A quick connect fluid connector that is detachably connectable to a fluid system to process a gas into or from the fluid system through the quick connect fluid connector. The quick connect fluid connector includes one or more temperature sensors that can sense the temperature of the gas within the fluid connector during processing. Based on the sensed temperature(s), an alert can be generated to alert a human operator conducting the processing and/or automatically shut-off the processing if the sensed temperature becomes too high. The operator will therefore be alerted if the cylinders are being processed too quickly or if the processing duration could be shortened.

A temperature transmitter assembly includes a thermocouple and a temperature transmitter. The thermocouple has a first conductor and a second conductor connected to each other at a junction. The temperature transmitter has diagnostics that determines a resistance of the thermocouple and based on the determined resistance, provides an indication of whether the first conductor and the second conductor are shorted together before the junction.

A protecting tube deterioration detecting apparatus applies a predetermined electric current to a measurement target thermocouple with protecting tube for a predetermined time, calculates a temperature rise amount of the thermocouple, and determines, when the calculated temperature rise amount exceeds a predetermined threshold, that the protecting tube is deteriorated.

Methods and apparatus to control heating based on monitoring feedback of temperature sensors are disclosed. An example heating apparatus includes: a heater configured to apply heat energy to an object; and control circuitry configured to: control the heater based on a target temperature to which the object is to be heated; in response to determining that a first measured temperature sample associated with a first temperature sensor is greater than a first reference temperature, updating a first temperature range and the first reference temperature based on the first measured temperature sample; and in response to determining that a second measured temperature sample associated with the first temperature sensor is not within the first temperature range, reduce the priority of the first temperature sensor for control of applying the heat energy to the object.
