SEMI-GAS® Debuts New GigaGuard(TM) Pressure Status Indicator

Low-cost controller monitors gas supply pressure

Malvern, Pa. – SEMI-GAS® Systems, an industry-leading provider of ultra-high purity gas delivery equipment, debuts its new GigaGuard™ Pressure Status Indicator (PSI) for monitoring gas supply pressure from 1 or 2 pressure switches with single or dual outputs. The compact controller is SEMI-GAS’ latest addition to the GigaGuard gas control product line and the manufacturer’s economical solution for indicating pressure changes in manual, non-hazardous gas applications where minimal facility monitoring is desired.

The new GigaGuard PSI features green, yellow and red indicator lights and an audible alarm to signify pressure conditions beyond the user specified set points. Should the pressure exceed the system parameters, an integrated LED button on the front panel allows the operator to manually silence the horn.

The GigaGuard PSI configuration can be accessed and adjusted with any web compatible browser. Configurable parameters include network communication settings, front panel LED behavior, and relay output configuration. While the controller comes standard with MODBUS TCP communications, remote monitoring is also available through the controller’s bottom-mounted Ethernet RJ45 port.

The GigaGuard PSI NEMA-rated ABS plastic enclosure is 4.25” high by 8.0” wide and 2.5” deep and comes with built-in brackets for easy wall or rack mounting. A 6’ AC power cord with 5-15p plug is provided; however, an external DC power source can also be used.

Dave Stetz, SEMI-GAS’ controls engineering manager, said, “The GigaGuard PSI is a new tool we are offering for our customers to make managing inert gas delivery simple and cost-effective. The new controller utilizes a streamlined design to provide necessary function while promoting safety, dependability, ease-of-use, and a minimal requirement for maintenance at a very favorable price point.”
