Vacuum Transducers for Digital Acquisition or PLCs


0-30" Mercury Vacuum Pressure Transmitters
HyVac has a number of pressure transducers in the low vacuum range that can be either hooked up to a programmable logic controller (PLC) or a digital acquisition (DA) system. The models are available with output in either 4-20 milliAmp or 1-5 volt output The transmitter is housed in a metal NEMA 5 approved enclosure. Because the output ranges from 0 to 30" hg vacuum or scale can be adapted to other scales. Use these economical pressure transmitters with clean, dry non-corrosive gases. These units are ideal for both your laboratory and industrial application. Solid-state design ensures reliability and provides an accuracy of +/-1%. Choose a transmitter with either 4-20 ma or 1-5 v output signal. Select a 4-20 ma model for excellent performance in noisy electrical environments; the transmitter uses a two-wire current loop system. Color-coded wiring makes installation easy. Units have a 1/8" MNPT brass fitting for incorporation into systems.
