High-spec temperature probe offers extended performance

The new compact probes are available in both PT100/1000 and NTC10K sensor versions and with enhanced IP67 environmental sealing, offer improved working and short term temperature range ratings over competitively priced alternatives. Both versions encapsulate the sensor element in a 4 mm probe tip to ensure a rapid response time and furthermore the materials and construction are UL compliant, which will help OEMs with safety certification.

Variohm EuroSensor has primarily designed the new ETP-AM-SP-IMC series for high accuracy coolant and/or oil temperature monitoring on performance autosports and special-purpose vehicles. But with its fast response time, wide environmental temperature range and excellent resilience to moisture, oils and chemicals, the sensor is equally well equipped for demanding medical and industrial applications. They may be used for example for measurement of liquids and gases in ambient environments where steam sterilising or intense washdown is necessary, such as medical autoclave equipment or high-hygiene processing machinery.

The PT100/1000 sensor version has options for PT100B and PT1000A elements with working temperature from -55 to +180⁰C - whilst the NTC10K version temperature range is slightly reduced at the lower end, to -40⁰C. Both versions have a short term rating to +230⁰C and response time in still water (t90) of just 7 secs.

Optional accessories include kits with mating connectors or complete mating cable assemblies, which all feature the Deutsch IMC connector with its ‘Ultem’ high temperature and corrosion resistant composite material – to ensure the complete installation will yield the highest possible performance and reliability.

Variohm EuroSensor has also released a version of the probe with an integral FEP screened cable assembly which does not offer all of the advantages of the IMC connector version but will be of interest to customers with less demanding range and environmental durability requirements.
