Dwyer Instruments 1950-1-2F ".4/1.6"" XPrf Differential # Sw"

".4/1.6"" XPrf Differential # Sw"

The 1950-1-2F is a .4/1.6" XPrf Differential # Sw with a -200 to 400 ppr maximum pressure differential and -.9"" Hg minimum pressure differential. The body is constructed with brass and the frame is constructed of chrome plated steel.

The Model 1950-1-2F one differential pressure transmitter features a 2-in. dial face and 0.4/1.6-in. XPrf connection with a 6 ft. power cord and a ¼ in. NPT wetted parts port. It is designed for use in the food industry as specified in NSF Certified (Pneumatic, Ordnance, and Electronics) ANSI/NSF Standard 61 for use in potable water systems, and meets applicable industry standards such as CGA G-4, UL 1585, ULC/CSA STD C22.2 No.

P30 XPrf Diff #/Sv/Cvr... Used to measure two-phase differential pressure in static or fluctuating conditions, according to the principles of capacitive displacement differentials.

The 1950-1-2F provides a differential pressure output of .4" w.g. to 1.6" w.g. with the 0-3 PRV model or 0-5 PRV model transducers for measurement of low and high level in compressors, blowers, vacuum, flow or pressure, as well as air/water temperature measuring applications. The entire range is housed in a rugged cast aluminum case enameled to prevent rusting or damage from the normal handling that some instruments experience."

The 1950 series, 1.6"" differential pressure switches are completely enclosed for maximum protection against dust and water infiltration. The 1950 series is accurate to within 0.1% of set point with a full scale deflection of 4? wg. This switch features an adjustable reset, an oversized rotary knob of the pointer type with automatic shunt and a rugged nickel-plated brass body with a socket contact arrangement for reliable operation over long periods of use. They are UL listed for water spray and generally usable as low as -20°C to a maximum temperature of +80°C (-4°F to 176°

The model 1950-1-2F 4X Pressure Regulator with Fuzzy Logic has a differential pressure gauge range of .4 to 1.6 inches of water and a pressure gauge accuracy of ±1%. It also includes 3-state Auto/Manual/Reset switching capability and is controlled by a microprocessor. The 1950-1-2F includes a 10 psi Precision Filter, Approaching Set Point Alarm, RS232 printout, Fuzzy Logic Assistance, built-in dew point monitor feature with Auto Recall, and features a user changeable default set point.

The 1950-1/2F High Range Differential Pressure Switches are non-relocking, snap action switches. They have a 3/4"" NPT male pipe thread inlet port. They have a damped snap plunger, 4-40 screw with lock washer and nylon spacer for the trip lever at the plunger. The maximum differential pressure is 2.5 psi at a differential temperature rise of 1000 F and assuming an ambient temperature of 77 degrees F.
