New Low-Cost Thermocouple Transmitters Feature Fast and Easy PC-based Configuration via USB Acromag expands their line of USB-configured head-mount temperature transmitters by releasing new thermocouple/millivolt input models with very high accuracy, linearity, and environmental stability

WIXOM, Mich., April 6, 2011 /PRNewswire/ -- The latest offering in Acromag's new ST130 series of low-cost, temperature transmitters is a thermocouple/millivolt signal conditioner, Model ST132. This model can convert sensor input signals from eight thermocouple types or a plus or minus 100mV range and output a proportional 4-20mA process control signal. The ST132 is an output loop-powered (7-32V DC) two-wire transmitter and very easy to use. Free Windows configuration software simplifies set up and downloads calibration settings to the unit through a USB connection. Units mount easily in DIN Form B sensor heads or on a DIN rail. The rugged, low-maintenance design also features a 24-bit A/D controller that delivers high accuracy and linearity with very low drift across a -40 to 80 degrees C operating range. Units are CE compliant with UL/cUL Class 1 Div 2 Zone 2 approvals pending. Despite the advanced-performance and features, the ST132 lists for only $89.

"Our new ST132 thermocouple transmitter offers great performance and convenience at a surprising price," states Don Lupo, Acromag's sales and marketing director. By leveraging the latest microcontroller technology, this transmitter is able to provide a performance level and feature set that was previously unavailable in a unit of this size and price. In addition to supporting numerous sensor types on a single unit, the ST132 performs signal linearization, and cold-junction compensation functions. It also supports reverse-acting (inverse) output and has a fast response time (as low as 8ms). The Windows configuration software helps you quickly program the transmitter using a USB cable connection to select input type, scale I/O ranges, set filtering levels, and choose upscale or downscale operation for sensor faults. Digital calibration eliminates zero/span pots, DIP switches, and pushbuttons for more precise measurements.

A rugged design helps these transmitters operate reliably in harsh industrial environments. Ambient temperature drift is less than 75ppm/degrees C for long-term stability. The ST132 is shock (50g) and vibration (5g) resistant and includes high-level electrical noise immunity (RFI, EMI, ESD, EFT, and surge protection). And to prevent incorrect wiring, the output/power connection is non-polarized.

For easy installation, Acromag sells a variety of mounting and wiring accessories. A USB-to-USB isolator protects equipment from ground loops, electrical noise, and surges during configuration. For convenience, a kit supplies the software, isolator, and USB interface cables. Numerous connection head enclosures are also available through Acromag. Select from stainless steel, aluminum, and cast iron housings with explosion-proof or general-purpose ratings. A DIN rail adapter adds more mounting options.
