Pipeline thermocouples & RTDs for Pipe-thread installation

Flow-Thru Thermocouples and RTDs - D4A Series Bookmark this page!
MALE and FEMALE NPT UNIONS

FLOW-THRU temperature sensors use either the NANMAC Right-Angle Ribbon Thermocouple sensor, or a Pt-100 Ohm RTD.

The Right-Angle thermocouple utilizes a special ribbon element which eliminates conduction error due to shallow immersion in to the flowing gas or liquid within the pipeline. Additionally, this ribbon design also provides response times in the low milliseconds.

All Pt-100 RTD devices are of sanitary design as the sensor is separated from the material within the pipeline by a 0.015 inch thick stainless steel diaphragm.

Thermocouples requiring sanitary design are also available by adding the diaphragm. to the thermocouple, contact the factory for more information.

-Female (F) union shown, Male (M) union also available-

Temperature Range is from minus 320 to + 1250 degrees F.
Pressures up to 4000 PSI
Response Time - Thermocouple = 20 Milliseconds. RTD = 3 seconds
Available in thermocouple types J, K, E and T; RTD is Pt100, 2 wire standard
Termination - 3/8 O.D. stainless steel tube with standard size 2 pin male plug attached. Other termination styles are available upon request, i.e. transition to flex leads, Explosion proof connector head, 3 or 4 wire RTD, etc.
Union Type - 316 Stainless steel male or female NPT union
Only RTD models come standard with sanitary design which features a 0.015 inch thick diaphragm. Thermocouple types with diaphragm. are available.
Special designs having ports of different dimensions are also available.

Special Note:

All units come standard with thermal junction flush to inner wall surface. If junction is to protrude into the stream, specify dimension " E" in increments of 1/16 inch, up to 1/4 inch.

EXAMPLE: D4A-10-K-M-E=1/16, Tolerance on "E" is 0.010

ORDERING INFORMATION
Specify Part No. Thermocouple Type or RTD and either Male (M) or Female (F) union.
EXAMPLE: D4A-4-K-M or D4A-12-RTD-F
