Murphy Pressure Transmitter Direct Mount Switch Model Psb Pd8100 Series Pxt K - China

price: contact company for price

The PSB switch is a direct mount switch for critical pressure points. It

has one limit contact that can be used to activate an alarm, actuate

indicator lights or shutdown equipment.

The construction of this instrument is the same as our time- proven Swichgage® instrument. A precision machined brass mounting plate and port captures a high quality stamped beryllium copper diaphragm. The single- pole, double- throw ( SPDT) snap- switch is operated directly from the diaphragm for quick acting and positive switching. Trip point is factory preset according to your specifications.

Housing is weather sealed to prevent entry of moisture, dust, etc. A glass- filled nylon terminal block with quick screw terminal connections gives the PSB switch a real advantage in industrial engine applications. The PSB is ideal when reading is not desired, but pressure is critical to operational efficiency.

Intended for use in general purpose nonclassified areas.

The PD8100 Series eliminates pointer flutter on pressure indicating SWICHGAGE® devices which are subject to pulsating pressure from reciprocating pumps or compressors. It also allows a close setting of high and low contact points providing for more accurate pressure indication and control of equipment.

The PD8100 Series decreases wear on geared movements and increases the life of pressure indicating instruments by eliminating excessive gage strain and unnecessary movement. A necessity which quickly pays for itself by protecting any pressure indicating and control instrument which is subject to pulsation.

• 4- 20 mA Output Signal

• Piezoresistive Pressure Transmitter

• Corrosion Resistant Construction

• High Stablity

The PXT- K Series pressure transmitters are state- of- the- art instruments providing 4- 20 mA output. Each Piezoresistive Pressure Transmitter contains a transducer comprised of a piezoresistive silicon chip mounted on a glass- metal feedthrough header welded into a stainless steel housing and filled with silicone oil; the very thin laser- welded stainless steel isolation- diaphragm completes the front side. Media pressure is transferred from the stainless steel isolation- diaphragm,  via the oil inside the cell, to the silicon measuring chip. This construction, combined with the advanced internal signal conditioning circuitry, results in a rugged instrument with extremely small temperature error and class- leading EMI/ RFI resistance.

The enclosure and all wetted parts are made of 316L stainless steel to meet NACE MR01- 75.

Applications: PXT- K Series Pressure Transmitters can be used in applications such as Compressors, Engines, Process Control, Liquid Level and Pumps.
