TSR - RTD Temperature Probes

Brand: KOBOLD Instruments, Inc

The KOBOLD TSR RTD temperature probe employs a resistive thermal device (RTD) to measure process temperature.

Using the relationship between resistance and temperature change in metals, these temperature probes provide a very stable and repeatable output.

This makes them well suited for industrial applications requiring a high degree of measuring accuracy over a wide range of temperatures.

They employ a Pt-100 RTD sensing element, which is hermetically sealed inside a 316 stainless steel probe. T

he TSR is available in an RTD-only version or RTD with head-mounted 2-wire, 4-20 mA transmitter. Both NPT or Tri-Clamp® connections are offered as standard.
