Dwyer Instruments 1910-10 Dwyer Series 1900 Compact Low Differential Pressure Switch with Conduit, Range 3.0-11.75"WC

"3/11.75"" DIFF.# Switch"

'The Dwyer Series 1900 Compact Low Differential Pressure Switch with Conduit, Range 3.0-11.75"WC WILL NOT frost, even when exposed to harsh industrial environments.

1910-10'', Series 1900 Compact Low Differential Pressure Switch with Conduit, Range 3.0-11.75"WC. 2-Pin #PST Sensor. 1/2"FNPT Enclosure Connection. 0-5PSI Gauge Connection.

The Series 1900 Compact Low pressure switch is an ideal, high quality differential pressure transducer. It is capable of measuring pressures from 3"WC to 11.75"WC and measuring flow from 0.090 ft3/min to 1.25 CFM. The Series 1900 compact switch is the standard for quiet operation and its housing meets IP67 ingress protection ratings for clean agents, weather conditions, vibration, altitude, and continuous high ambient temperatures (40 C max).

A compact and economical differential pressure switch with an integral 1/8 NPT (Female) outlet designed to fit inside of the pipe run utilized to supply the instrument. Differential pressure (DP) sensing element provides repeatability of readings within 0.1% over an absolute range of 3.0''WC to 11.75''WC and standard zero setpoint accuracy of 0.25% of full scale. The switch is normally open at 0.00''WC and closed when a preset or alarm value is reached, providing a two position DP control or alarm output signal.#

1810 Series Pocket-size Differential Pressure Switches are available with a wide range of selectable settings and rated for use with gases, liquids or combinations thereof. These compact, low-profile, anodized aluminum switches feature either a locking ring or setscrew that securely holds the adjustment shaft in place. The case is keyed to prevent the settings from being changed accidentally.

The Series 1900 Compact Low Differential Pressure Switch is a general purpose switch that can be used for pressure or vacuum signal indication.

Differential pressure sensing for monitoring on/off flow of gas, liquid, steam, or air with optional electrical output. A simple differential pressure switch uses a diaphragm (plastic or metal) that flexes under pressure to vary the vacuum on a balanced vane anemometer built into the case. A small cadmium switch mounted between the moving vanes completes an electrical circuit as the diaphragm flexes. Differential pressure is then given by the ratio of the voltage to a fixed reference system."
