Description
dV-2 PS – an excellent digital manometer with two independent relays. The manometer uses Keller microprocessor technology, which allows for results with very high accuracy. All measurements are compensated across the entire measurement range and temperature range, resulting in an error of no more than 0.2% FSO. The manometer has two built-in independent relays for triggering at the Upper and Lower pressure levels. The device contacts are quite durable and do not wear out over time. The relays are programmed directly using two buttons and a convenient menu. Alternatively, the dV-2 PS can be connected to a PC or laptop via the RS485 interface, using Keller software "Pressure Switch Console". User settings can be stored on the computer for further use. Pressure can also be displayed and recorded on the computer for diagnostic purposes using Keller software Read30.
The two independent relays operate separately for switching contacts and turning additional equipment on and off. Hysteresis can be set for each relay. This makes the dV-2 PS series an ideal device for automation systems. The relay status is displayed on the side of the LCD screen.
