We offer standard, configure-to-order and
engineer-to-order probes. We are able to engineer and
manufacture a custom thermistor probe solution according to
your specifications by combining a thermistor component,
probe housing, lead configuration and connector where a
surface, air, gas or liquid temperature sensor probe is
required. We can engineer probes designed specifically for
your requirements thus ensuring design challenges are
overcome, your probe will be cost-effective in high volumes,
and you will have customer-specific revision control.
Contact us today with your requirements.
Please see below for examples of
customized probes:
Customer-specific connectors:
Fabricate 400 or 700 Series Patient Temperature Probes with
customer-specific connectors to meet instrument
requirements. Modifications may range from color coded
backshells to shielded cables and custom connector systems.
Radio Frequency Interference (RFI):
Specially design a disposable probe to minimize
susceptibility to RFI and EMI for a pediatric/neonatal
application in order to meet CE/MDD requirements.
High stability probe: Special design
of a glass encapsulated thermistor sensor in a stainless
steel housing used in conjunction with the high accuracy
4610 thermometer system for field calibration of blood
analyzing machines.
Sensor in a hex head cap screw: This
application uses an epoxy-encapsulated thermistor potted in
a #8-32 x .250" hex head cap screw. This probe is given the
full range of tests per MIL-PRF-23648 over a temperature
range of -65 to +125C. It is the most severely tested part
we manufacture; we have built it for four years. It is used
in an unmanned space application where long-term reliability
is critical.
Sensor in a small surface temperature
probe: This application uses an epoxy-encapsulated
thermistor potted into a small surface sensor package with
twisted pair leads to monitor the temperature in electronics
units on the ISS. This probe is given the full range of
tests per MIL-PRF-23648 over a temperature range of -65 to
+125C. We have built hundreds of these probes for the same
customer since 1997.
Sensor in a threaded stainless steel tube:
This application uses a small bead-in-glass thermistor
potted in a spring-loaded, steel tube, threaded housing.
This part is tested to portions of MIL-PRF-23648 per
customer specifications. We have been supplying this part in
several configurations to the same customer since 2000.
Temperature Sensor in a Stainless Steel
Tube: This application uses a 55000 Series glass
encapsulated thermistor mounted in a rolled-end stainless
steel tube and is being used to measure the temperature in a
bore hole 10,000 feet into the earth’s crust at the bottom
of the Marianas Trench, 35,000 feet deep under the Pacific
Ocean. Since service calls are difficult to schedule,
obviously reliability and accuracy are critical.
Redundant sensors in a precision machined
brass housing: This application uses dual 0.1°C
interchangeable glass encapsulated sensors in a brass
housing to provide failure proof monitoring and control of
super computer micro-processor temperatures. The hermetic
seal of the sensor provides years of stable control of the
temperature in this critical application.
Surface temperature sensor matched with a
4800: This application uses a precision sensor mounted
in an attachable surface temperature probe matched and
calibrated to a 4800 Linearizing Circuit. A series of these
probe circuits are used to precisely measure changes in
surface temperature in a radio telescope made up of 2,004
individually positionable panels which control the shape of
the structure within a few thousandths of an inch. Thermal
expansion can cause the surface to distort due to uneven
heating from the sun. Changes in temperature cause
distortion to the tightly controlled dimensions of the
antenna dish, and temperature monitoring allows for
compensation to the incoming signals.
