## NTC Miniature Series 

Thermometrics Thermoprobes 

## Applications 

## **NTC Type P20, P25 and P30** 

- Miniature bead-in-glass probes feature high reliability, ease of handling and very fast response time. The longer body length makes them particularly well-suited for applications where fast response and immersion in fluids are the major requirements. 

## **NTC Type P60, P65, P85 and P100** 

- Thermoprobes are recommended for all low cost , general purpose applications involving temperature measurement and control, circuit temperature compensation, liquid level sensing or fluid flow sensing. They are ideally suited for applications, that require a reliable, low cost sensor. 

## Descriptions 

## **NTC Type P20, P25 and P30** 

- The Type P20, P25 and P30 miniature thermprobes consist of a small bead thermistor hermetically sealed in the tip of a shock-resistant solid glass rod. The miniature thermoprobes have improved stability over glass coated and ruggedized glass bead thermistors. 

## **NTC Type P60, P65, P85 and P100** 

- The Type P60, P65, P85 and P100 thermoprobes consist of a large bead thermistor hermetically sealed in the tip of a shock resistant solid glass rod. They have excellent long-term stability.

## Type 60/65/85/100 Specifications 

All thermoprobes are aged for extended periods of time. As such, they exhibit excellent stability for all service temperatures at or below the aging temperature. Thermoprobes that are manufactured with material system “E” are aged at 221°F (105°C); those manufactured with a material system having a 77°F (25°C)/257°F (125°C) ratio of 16.9 or less are aged at 392°F (200°C); and all other material systems are aged at 572°F (300°C). Intermittent operation at temperatures up to 1112°F (600°C) is permissable, however, degraded stability will result when the aging temperature is exceeded. This appiles to the NTC Type P20/25/30 also.
