Multi-Channel Temperature Transmitters

With two independent temperature transmitters inside a single inch-wide unit, Acromag's 600 Series thermocouple and RTD transmitters can cut your costs by more than 30%. It's like buying one transmitter and getting the second for only $70. And since the second transmitter shares the same housing, it doesn't require any additional space. Easy push-button calibration saves you time on installation and maintenance to further reduce your expenses.

The 655T and 656T models accept universal thermocouple and millivolt input signals, provide isolation, and output proportional DC current signals. 657T and 658T transmitters convert universal RTD or resistance input signals to DC current output signals. The outputs on all models can also be linearized to the input sensor signal. These loop-powered transmitters are ideal for panel shops and end-users who require a high-density signal conditioner that can cover a broad range of temperature measurement applications.

RTD units are priced at $200 and $270 for single-channel (657T) and dual-channel (658T) models respectively. Single channel thermocouple transmitters (655T) sell for $220 with dual channel (656T) models starting at only $300. On the dual channel units, each channel operates independently. Thermocouple inputs are isolated from each other to prevent interaction between channels.

A dual channel transmitter with DC voltage inputs, the 654T, is also available. It sells for $280

Acromag mourns passing of founder, President, and CEO Henry W. Patton II.
A key figure in the development of signal conditioning technology, Henry W. Patton II, founder and President/CEO of Acromag, Incorporated died on July 23, 2003. Friends and family joined together to mark his passing with deep sadness in honoring their well-respected colleague. Mr. Patton pioneered the use of magnetic amplifiers for process measurement applications. As a young engineer at Collins Radio in Cedar Rapids, IA, Mr. Patton realized the mag-amp’s potential for measuring low-level sensor signals and founded Acromag, Inc. in 1957 in Detroit, MI. more

Ask the I/O Experts
Question: Can we use isolators before thermocouple signals?

Answer: Thermocouples are low-level millivolt sensors that typically come in contact with the process. Very long thermocouple runs can be affected by what's know as "immersion error." Immersion error occurs when the thermocouple extension wire acts like a heat sink to hotspots near the wire run, i.e., hot water pipes. The wire will conduct the heat causing the dissimilar metal junctions to change in temperature, thus causing more errors. Therefore, to increase the integrity of a thermocouple measurement, an accurate and stable amplifier combined with isolation should be placed as close to the sensor as possible.

For systems with widely distributed measurements, single-loop, field-mount transmitters are typically used. Otherwise, for centrally wired panel applications, DIN rail-mount transmitters are ideal.
