The IPS-300 Ultra High Purity Indicating Pressure Switch is designed to provide economical pressure monitoring with setpoint indication of the high purity, toxic and corrosive gases used in the semiconductor manufacturing industry and gas distribution Systems. In addition to providing accurate (±2% of span) indication of gas pressure, this 2 inch diameter instrument incorporâtes a magnetically actuated, switch capable of operating low voltage annunciators, lights or relays. When used with the appropriate pull-up or pull-down re-sistors, the monitor can be connected to the input port of a microprocessor or to a logic network. It may also be used as an input to a programmable controller. Moving the colored index on the front dial to the de-sired set point sets the switch. A small magnet fastened to the indicating pointer actuates the switch. A magnetic latch on the switch permits the switch to remain “on” or “off” after the pointer passes the operating point, without restraint on the indicating pointer. The switch can be factory ordered to close on in-creasing pressure (HA) or close on decreasing pressure (LA). The switch action will be noted on the tail of the pointer. The IPS-300 Pressure Switch offers the ease of ad-justment and economy that permits field use of several units covering a variety of pressure range set-points. It is also a low cost alternative to analog transducers with A/D conversion for digital input to PLCs and micropro-cessors. The IPS Pressure Switch provides many advantages over other instruments, including: fast, easy, accurate setting of set points; pressure and setpoint indication on the same dial face
