Gage / Switches - Digital

Digital Gage Switches, such as the Digihelic® Series, are multi-functional instruments that combine a digital pressure gauge, a pressure switch, and a transmitter into a single device. They provide a clear digital readout of pressure while allowing users to program specific setpoints that trigger internal relays for automated control.

By combining a gauge, switch, and transmitter, these devices reduce the need for multiple separate instruments, lowering installation costs and saving space on control panels. This integration also simplifies calibration and maintenance, as there is only one device to service for three critical functions.

Yes, the collection includes specialized models like the Series AT2DH3, which is ATEX-approved. These units are housed in flameproof enclosures, making them safe for use in hazardous areas where combustible gases or dust may be present, such as in petrochemical plants or grain silos.

The collection features the Digihelic Links™ Data Acquisition and Logging Software. This allows users to connect their Digihelic® controllers to a PC for real-time monitoring, data logging, and remote configuration, which is essential for detailed process analysis and compliance record-keeping.

These instruments are ideal for high-precision tasks such as monitoring pressure drop across industrial filters, controlling fan speeds in HVAC systems, and maintaining specific pressure levels in cleanrooms or laboratory fume hoods. Their high accuracy ensures that even minor pressure fluctuations are detected and managed.

While digital instruments are highly stable, their internal sensors can still experience drift over time. HK Calibrations provides professional calibration to verify that the digital display, the switch trigger points, and the 4-20mA transmitter output all remain within their specified tolerances, ensuring continued safety and process efficiency.
