100 ohm RTD Sensor with Potting Adaptor

These rigid sensors have a stainless steel welded closed end sheath. The RTD sensing element is 0.4” long and is placed at the tip of the sheath which means that the minimum immersion depth should be at least 2”. The sensor is rated up to 540ºF. They are terminated with a potting adaptor which allows the attachment of the 72” long PFA extension leads.

100 ohm RTD Sensor with a Size 1 Lemo Style Connector

100 ohm RTD Sensor with a Size 1 Lemo Style Connector These rigid sensors have a stainless steel welded closed end sheath. The RTD sensing element is 0.4” long and is placed at the tip of the sheath which means that the minimum immersion depth should be at least 2”. The sensor is rated up to 540ºF. They are terminated with a size 1 Lemo style plug or jack. Ideal where quick disconnection is required near to the sensor. Mating connectors and a variety of extension cables and adjustable compression fittings can be found in this catalog to complement this product.

Sheath: 316 Stainless Steel 0.125” OD
Variety of lengths available. Length shown does not include the plug or its adaptor
Operating range: -100ºF to +540ºF (-75ºC to +280ºC)
Terminated in a size 1 Lemo style plug or jack. Mating connectors are available separately

100 ohm Precision RTD Sensor

This precision RTD sensor can be used as a temperature reference for comparison of other temperature sensors or alternatively as a high accuracy RTD sensor for exacting temperature measurement. Sensors supplied complete with calibration certificates are also available.
100 ohm RTD element, Alpha = 0.00385, Class 1/10
Accuracy of element: ±0.06ºC equating to a typical sensor accuracy of better than ±0.12ºC at 0ºC
This is a 4 wire device; however, it can easily be used for three wire applications by omitting to connect up one of the white leads
Recommended minimum insertion length: Typically at least 6”
Sensing area: The first 0.787” from tip
Operation range: -58ºF to +480ºF (-50ºC to +250ºC)
Sheath: 316 stainless steel 0.125” or 0.250” dia x 10” long
Leads: 72” PFA insulated
Sensors available with a standard three point calibration certificate at 32ºF, 212ºF and 400ºF or alternatively choose your own points

100 ohm Miniature RTD Sensor 0.020” to 0.062” diameter

These miniature RTD sensors are available in either 0.020”, 0.032”, 0.040 or 0.063” diameters. They have an incredibly fast response time compared to larger diameter sensors and are ideal for applications such as laboratories or applications where response time is critical. They are supplied as four wire devices but by simply selecting only two red and one white leads they can also be used as three wire devices. The sensor is rated up to 660ºF. They are terminated with a potting adaptor which allows the attachment of the 36” long PVC extension leads.
4 wire configuration (but also suitable for 3 wire configuration)
100 ohm RTD element, Alpha = 0.00385, Class A
Sheath: 316 Stainless Steel 0.020”, 0.032”, 0.040” or 0.062”
4” or 8” long versions available. Length shown does not include potting adaptor or leads
Operating range: -100ºF to +660ºF (-75ºC to +350ºC)
Terminated in a potting adaptor rated to 220ºF
Extension Leads: 36” long, 24 AWG stranded PVC insulated wires with a PVC oversheath. 4 wire - 2 colored red and 2 colored white (can be used as a three wire device by not connecting up one of the white leads)

100 ohm Rugged Self Adhesive Patch RTD Sensor

This rugged sensor incorporates a silicon rubber patch with a Pt100 thin film element within, attached to 72” long PFA leads with stainless steel braided leads. The patch is self adhesive and when placed in position enables good response times from the flush mounted RTD element.
Thin film 100 ohm RTD element, Alpha = 0.00385, Class B
Rubber Patch dimensions: 1.57” x 0.55” x 0.28” maximum depth
This is a 4 wire device; however, it can easily be used for three wire applications by omitting to connect up one of the white leads
Sensor housing: Silicon rubber with self adhesive backing
Operating range: -58ºF to +300ºF (-50ºC to +150ºC)
Leads: 72” PFA insulated, stainless steel braided
