Fast Response Platinum Resistance Thermometers

Netsushin's UNR-14 probes have small diameters and very small sensing elements. These small size improves response time, allowing measurements to be taken more quickly. The probe transitions directly to lead wires without the use of transition sleeve. The shape is ideal for applications with space limitations.

Features

  • 1. The smallest Platinum wire wound RTD
  • 2. Small aging variation.
  • 3. Better Reproducibility at the measuring temperature
  • 4. Better sensitivity.
  • 5. Higher stability because of lower self-heating.

Specification

Diameter 0.5mm Sheath pipe is available.

Ceramic elements are very fragile and generally assembled into probes. We have developed ultra small elements that have enabled to make probe size smaller and shorter.

Heat transfer to the sensor occurs quickly.

Time constants from 0℃ to 100℃ are as fast as 0.4seconds.
This sensor has low heat capacity and responds to even slight changes in temperature.

Custom options available

We can supply the sensors designed to meet your requirements. Custom sizes and shapes are available, regardless of the quantity. contact us for a price and delivery information.
