Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 
Thermistors are thermally-sensitive devices whose electrical resistance varies with temperature. Unlike RTDs and thermocouples, thermistors do not have standards associated with their resistance vs. temperature characteristics or curves
Search by Specification | Learn MoreTemperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation).
Search by Specification | Learn MoreOscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs.
Search by Specification | Learn MoreSignal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.
Search by Specification | Learn MoreThermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes. They are typically used to control heating and cooling systems.
Search by Specification | Learn MoreDigital thermometers are portable temperature sensing devices that have permanent probes and a digital display.
Search by Specification | Learn MoreThermistor temperature probes sense temperature by using thermistors, devices made of semiconductor materials which exhibit a large change in resistance for a small change in temperature
Search by Specification | Learn MoreTemperature probes are used in various temperature sensing applications. Technology options include thermocouple, RTD, thermistor and solid state style probes

The AP thermistor uses new production techniques to create an interchangeable thermistor at a fraction of the cost of conventional NTCs. The AP is interchangeable to +/-0.5°C (0-70C) and better than +/-0.2°C over 5-40°C thus making it ideal for thermostat applications. It is also extremely stable from -60/+150°C making it highly suitable for automotive and appliance applications. (read more)
Leaded NTC thermistors are some of the most versatile temperature sensors available to the design engineer. These products are offered in many different lead configurations, uninsulated or insulated, and with coating/encapsulation sizes ranging from 0.125 in OD down to 0.020 in OD. (read more)
Because of its unique metalization technology [patent/patents pending] and superior thermistor processing technology, the Cornerstone Sensors, Inc.
