Industrial temperature transmitters

Minco's Temptran™ RTD transmitters provide a 4 to 20 mA signal that can be sent over long distances with a simple 2-wire system. Add any Minco model transmitter (except electrically isolated models). See Section 5 for complete details and ordering information.

Special high-accuracy calibration: For guaranteed system accuracy of ± 0.75% of temperature span, specify transmitters with high accuracy calibration. Calibration data traceable to NIST will also be provided. Get more information on page 5-18.

Specification and order options

- CONDUITTHREAD

SHOWN WITH STAINLESS STEEL HEAD AND UNION/NIPPLE EXTENSION

Overview

Sense temperature in high-pressure fluids and gases. These assemblies are spring-loaded for positive probe contact against the bottom of the thermowell.

• 316 stainless steel thermowell

• RTD probe for use to 550°C (1022°F)

• Spring-loaded probe

• Cast iron, stainless steel, or aluminum connection head

Note: For temperatures less than 260°C (500°F), assemblies using tip-sensitive sensors are recommended.
