| | Jun 14, 2011 — Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, is announcing the release of its NEW SERIES 1831 DPDT LOW DIFFERENTIAL PRESSURE SWITCH.
One of our most popular differential pressure switches is now available with a DPDT switch output. The 1831 combines small size with 2% repeatability. Absolutely no power is required to operate the DPDT switch. Set point adjustment on the switch is easily accessible for modifying the set point. The 1831 is a manual reset that activates on an increase in pressure. Ranges as low as 2.5 in w.c. all the way to 23 in w.c. are available from stock.
The unique non-powered design eliminates many of the common problems associated with existing switches in high duct static cutout installations. A mounting bracket is included which simplifies installation. | |
