With advances in technology Thermal Components now offers high temperature thermistors to a maximum 500°C .  This now opens up thermistors to be used in applications where RTD’s have been the preferred option. Two versions are available 1K ohm @200°C and 4K ohms @ 200°C. The patented design involves the use of a new high temperature glass encapsulation of the chip. The glass enveloped chip is then neatly aligned with a ceramic base which allow a neat package along offering long term stability. Leads are 71mm dumet wires. This allows for the high temperature thermistors to be easily housed in a stainless steel tube with ceramic tube to insulate the wires in the tube. A wide range of custom designs are available for different applications

Characteristics

• Max operating Temperature…….500°C
• Thermal Time Constant……. 18 secs

High Temperature Probes

High Temperature Probes for a range of applications where standard epoxy thermistor will not tolerate the ambient temperature. Range of hi reliability glass thermistor offer stability at higher temperatures.

High Temp Probes 200°C

Glass NTC thermistor packaged in a Stainless steel housing, for mechanical protection, using Silicon sheathed jacket with FEP insulated wires. Double radial crimp applied to ensure strain relief. The insulation also offers resistance to certain chemicals and UV resistant. A range of NTC resistances and tolerances are available to suit customer requirements

High Temp Probes 250°C

Glass NTC thermistor packaged in Stainless steel housing using braided FEP insulated jacket with FEP insulated wires. Double radial crimp applied to ensure strain relief

Ultra High Temp Probe 500°C

Launching soon will be an ultra high temperature probe which can tolerate 500°C. Utilizing patented glass sintering this new NTC will offer design engineers the opportunity to replace RTD’s. Special hi temp ceramics will be used for protection.

Applications

• Solar Roof sensors
• Gas flame monitoring

New stainless steel humidity filters for harsh environments. A porous sintered head allows airflow but not environmental contaminants. Digital and analog humidity sensors are easily accommodated in the space provided. 316 stainless steel provides a long term durability. Detachable head allows for easy replacement in the field with 3 0r 4 pin connector system

Deep Water Temperature Probe

The Deep Water Temperature Probe is universally by Scientific and Meteorology organisations to reliably and accurately measure deep water temperatures. The deep sea probe is designed for long- term immersion at considerable depth using a stainless/ neoprene vulcanised seal with a moulded external splice protector. The deep water temperature probe can withstand the forces of pier mounting in high wave environments. The deep water temperature probe is ideal for applications that include deep water reservoirs, wetlands, wells and tidal stations.

Data Sheet

Thermal Components  range of Pipe Temperature Probes offers HVAC engineers 2 new sensors that measure pipe surface temperature. These easy to fit clip on Temperature Probes are unique in performance necessary to measure straight and curved bend compressor and condenser coils for refrigeration applications. Available in a range of different NTC thermistor resistances. Pipe size is 3/8″ diameter. The sens-a-coil pipe temperature probes offers HVAC engineers the unique opportunity to measure the temperature on the bend of the return coil. In the past this has been difficult to achieve, however the patented system now is an easy clip on solution. Because the thermistor is housed in a small brass bulb which offers fast response time to refrigerant temperature changes.

The standard straight line pipe temperature probe offers an economical solution combined with fast response time through small diameter copper housing that is then overmoulded for mechanical and moisture protection.

Thermal Components new Pool Spa Temperature Probe features a rubber covered glass NTC temperature sensor encapsulated in a plastic housing . This offers superior waterproofing along with an easy push fit application iserted into a 3/8″ hole. This ensures a long field life and reduction in costs of replacement. Comes with a 4.5 Mtr lead length
