產品特色
● Display Units: psi, kg/cm?, bar, in Hg, ft w.c., kPa, MPa, %FS, in w.c., mbar, cm w.c., mm Hg, or oz/in? (choices depend on range).
● Test Mode: Simulates input over the range without pressuring to easily test switches and transmitter output feature.
● Fail-safe: For sensor failure, over pressure, high temperature limit, low temperature limit, or keypad short. User chooses if relay is de-energized, energized, or no action. With transmitter option, user chooses an output of 3.6 mA 22 mA, or no action.
● Alternation: Selectable alternation of set points between the relays for even wear on duplex pump applications.
● Versatile Compact Package: Can replace a separate gage, two switches, and a transmitter in a system saving, money, installation time, and panel space.
● Fully Programmable: To meet simple or complex application needs.
● Weatherproof Housing: Ideal for a wide variety of applications with panel mount, flush mount, or pipe mount ability.
