Series 616K & 616OT
Differential Pressure Transmitter
Cost Effective for B.A.S. Applications, Digital Push-Button Calibration with One-Touch® Transmitter Technology


The Series 616K & 616OT Differential Pressure Transmitters with One-Touch® technology
are designed for simplicity making them the ideal choice for installers and maintenance professionals.

The One-Touch® Differential Pressure Transmitters are cost-effective, compact transmitters that reduce up front costs as well as expenses over the life of the product. These instruments not only alleviate cumbersome turn pots typically found in most transmitters, but eliminate entirely the need to span the instrument during calibration. With a single digital push button, both ZERO and SPAN are calibrated properly, nothing else is required. No additional reference pressure sources and separate calibration devices are necessary; no need to remove from service and send to a lab. All that is required of the installer or user is to let the unit sit at zero reference pressure, then push a button. That is it! The transmitter is now ready for operation. Time savings are enormous over the life of the product compared to traditional transmitters which require time to annually remove the product for service plus the additional time to actually perform a complete full-span calibration.

Mounting is simple with integral mounting holes on the 616K or mounting tabs on the 616OT that are inherent to the molded housing. The Series 616K has easy-to-wire open screw terminals at the top of the housing while the Series 616OT possesses a convenient removable terminal block that allows the installer to wire externally, then snap the wired block back onto the board inside the enclosure. The Series 616OT provides an enhanced NEMA 4X (IP66) enclosure.

The One-Touch® family of Differential Pressure Transmitters are ideal for building automation applications such as air handlers, duct pressure, variable air volume and filter monitoring. Available models include ranges from 1" w.c. to 20" w.c. depending on series.
