Acromag models TT230 and TT330 Temperature Transmitters

The TT230 and TT330 process transmitter series continue to provide greater versatility with our new additions. Whether you need 2-wire or 4-wire transmitters, we can accommodate a wide array of process measurement/control applications.

Wixom, Michigan (PRWEB) November 14, 2013

Acromag’s new offerings in the TT230 and TT330 series of process transmitters are designed to deliver flexibility while maintaining optimal performance. These isolated signal conditioners feature high-density mounting on DIN rails, supporting RTD/resistance and potentiometer/thermistor input signals. With a convenient USB connection to a PC, precise configuration using Windows software is simple. Wiring terminals are front-facing and removable for easy connections and maintenance.

“The TT230 and TT330 process transmitter series continue to provide greater versatility with our new additions,” explained Don Lupo, process group sales and marketing director. “Whether you need 2-wire or 4-wire transmitters, we can accommodate a wide array of process measurement/control applications.”

Each model accommodates a variety of signal types selected in the configuration software. The TT234 and TT334 models interface 100-100k ohms via potentiometer/slidewire or 100-1M ohms from a thermistor/rheostat. The TT235 and TT335 models accept 100 ohm, 200 ohm, 500 ohm, or 1000ohm platinum RTD; 120 ohm nickle RTD; 10 ohm copper RTD; or 0-450 ohm linear resistance. All units effortlessly convert the input signals to a proportional current output signal of +/-20mA, 0-20mA, or 4-20mA. The TT330 series also allows for +/-10V, +/- 5V, 0-5V, and 0-10V output signals as well. The software also lets you precisely scale input ranges for full resolution. You can then test or calibrate input/output values in the software, too.

TT230 process signal converters have the option of loop-power with a 2-wire connection, or DC-powered with a 3-wire connection. TT330 process signal converters are DC-powered (12-32V) and support a bussed rail power option for primary or redundant power. The rugged design of these thin transmitters feature CE approval as well as: -40 to 80 Degrees C operation, electrical noise immunity, and surge protection. UL/cUL Class 1 Division 2 Zone 2 hazardous location approvals pending. Prices start at $175 (TT230 series) or $220 (TT330 series) for single quantities.

The USB-to-PC connection for software-driven configuration makes setting ranges and calibration easier, more accurate, and very reliable. Many competing units use DIP switches that can only offer coarse range settings, not fine adjustments. Using trim pots can allow fine tuning, but they require far more time to achieve the desirable results. With a USB port, you can digitally set the calibration gain and offset using precision D/A converters whereas DIP switches and pots can change values over time or due to temperature/shock/vibration. These changes can lead to drift and require periodic re-calibration. And once configured, the device’s settings can be archived in a file or uploaded quickly into additional units for rapid cloning in large systems. Later, a device’s USB port enables diagnostic communication using software while a unit configured with DIP dipswitches and pots cannot. Plus, USB-configured devices use fewer mechanical parts which increases long-term reliability.

All TT230 and TT330 models deliver high accuracy, stability, surge suppression, noise immunity, and fast response. They also withstand 25g shock and 4g vibration to deliver dependable operation in hostile environments. Built to AS9100 aerospace and ISO 9001 certified quality control standards and backed by a 2-year warranty, you can rely on Acromag’s instruments for long-lasting superior performance, even under the toughest conditions.
