Type-2581 Pressure Switch baileymackey

Type-2581 Pressure Switch baileymackey range of Pressure Switches is built to the high standards. Pressure Switch baileymackey. Pressure Switch baileymackey . BaileyMackey range of pressure transducers is designed for a wide variety of industrial applications. this series of pressure switches can be used for applications where an electrical circuit is required to close or open at required pressure. Type 1381 can be mounted directly on the connecting thread. Type 2581 baileymackey Pressure Switch measures pressure relative to atmospheric pressure and are divided into three main groups, each group being based on a different measuring principle. Baileymackey Diaphragm pressure switches can also be set to switch in vacuum

DATASHEET

ALTERNATIVES

Maximum Pressure

To ensure long service life select the pressure range as follows: Dynamic pressure applications Pmax = 75% of Range Static pressure applications Pmax = 100% of Range Maximum pressure that can be applied is 125% of pressure range (see option Q page 8 for higher pressures.)

Electrical Ratings

10 amp at 250V 50 Hz Inductive load 1 amp at 30V dc Inductive load For other voltages and currents please consult our technical department.
Setting Accuracy ...............±2%
Temperature Range.............–10 to +85ºC (Process fluid must not solidify)
Temperature CoeffIcient.......0.05% of range per ºc from 20ºC

Installation

These pressure switches can be mounted directly on the connecting thread. Sealing groves are machined onto the end face of parallel threads for use with sealing washers. A Mounting Bracket is available if required.

Vacuum Setting

At ambient pressure the switches will be in the operated condition consequently the wiring should be reversed i.e. NO becomes NC.

Connecting Threads

All connecting treads used in industry are available including British, American and metric. Please state the connection thread when ordering.

Flanges & Hygienic Fittings

Flanged fittings are available and all types of Hygienic fittings can be supplied assembled directly onto the pressure switch. If flush diaphragms are required please consult our Technical Department

Chemical Protection Series 1000

Pressure Conditions: Standard materials for wetted parts are brass pressure chamber and beryllium copper diaphragm. This can be changed to make the wetted parts suitable for most other fluid applications. The diaphragm can be protected against corrosion, by a thin sheet of suitable material and the pressure chamber can be electro-plated or machined from a suitable material either metal or plastic. Examples of suggested materials for use with a range of chemicals are given in the tables below ; these are only suggestions and it is the users responsibility to ensure that the material used is compatible with the chemicals used and the application conditions of concentration and temperature.

Vacuum Conditions: Diaphragm protection under vacuum conditions must be integral with the diaphragm. On vacuum applications or where suction can occur a 17/7 precipitation hardened stainless steel can be used as an alternative to beryllium copper. 17 / 7ph is less corrosion resistant than 316 stainless steel but it can be hardened and tempered to give reasonable spring properties. If this is not sufficiently resistant for the application the beryllium copper diaphragm can be electroplated or coated with a suitable plastic material.

Marine & offshore industry recommend to use Type 1381 Pressure Switch baileymackey. They recommend Type 1381 Pressure Switch baileymackey. Type 1381 Pressure Switch baileymackey function is to provide systems with electrical feedback in response to measuring a rise or fall in pressure. A pressure switch is usually adjustable with regard to the chosen set point of operation. Also known as pressure sensors, they are used to respond to fluid pressure. Type 1381 Pressure Switch baileymackey can be installed in container ship, chemical vessel, oil tanker, bulk carrier and Type 1381 Pressure Switch baileymackey can be installed in engine room. Type 1381 Pressure Switch baileymackey are widely used in industry to automatically supervise and control systems that use pressurized fluids. Another type of Type 1381 Pressure Switch baileymackey detects mechanical force; for example, a pressure-sensitive mat is used to automatically open doors on commercial buildings.
