Transmitter Cuts Installation & Calibration Time

Dwyer Instruments, Inc., recently released its new Series 616OT One-Touch Differential Pressure Transmitter. This compact transmitter reduces up-front costs as well as expenses over the life of the product, according to the company.

The 616OT One-Touch Transmitter alleviates cumbersome turn pots typically found in most transmitters, and also eliminates the need to span the instrument during calibration. With a single digital push-button, both zero and span are calibrated properly, according to Dwyer. No additional reference pressure sources and separate calibration devices are necessary; there is no need to remove the instrument from service and send it to the lab. All the installer or user needs to do is let the unit sit at zero reference pressure, and then push a button. Time savings are significant over the life of the product compared to traditional transmitters, which require time to annually remove the product from service as well as the extensive time to actually perform a full span calibration.

Available models include ranges from 10˝ to 20˝ w.c. Units come in a compact NEMA 4X (IP65) housing. Mounting is simple with back mounting tabs that are inherent to the molded housing. Wiring the transmitter is quick and convenient with a removable terminal block that allows the installer to wire externally, then snap the wired block back onto the board inside the housing.
