B-Series Switches – Pressure, Differential

Pressure, Temperature & Hydraulic

Ashcroft Inc. supplies highly reliable

Ashcroft

switches and controls for indus-

trial and process applications. We begin

with rock-solid designs, matching the most

appropriate technology with the safety and

reliability requirements of the applications.

The materials of construction are specified

to Ashcroft’s exacting standards, and prod-

uct is built to last in the toughest applica-

tions. Our modern, responsive manufactur-

ing facility is supported by an extensive

network of stocking distributors and factory

sales offices located in virtually every part

of the world. Special application assistance

is always just a telephone call away.

The Ashcroft B-Series switch line is

designed to satisfy most switch require-

ments. Materials of construction have been

selected for long life. A wide variety of pre-

cision switch elements are available to

meet every application requirement,

including hermetically sealed contacts for

added reliability and safety. The actuators

we use have been proven in more than 20

years of service in the world’s plants and

mills. Special designs are available for fire

safety, NACE, limit control and other more

stringent requirements. Simplicity and

ease of use are stressed to improve relia-

bility of the installation.

Applications include: pumps, compres-

sors, washers, filters, degreasers, evapora-

tors, recovery systems, food processing,

ground support equipment, reverse osmo-

sis systems, heat exchangers, hydraulic

systems, lubrication systems, marine

equipment, textile machinery, heating and

air conditioning equipment.

Thermowells

Thermowells must be used on any appli-

cation where the stem of the temper

ature

switch may be exposed to pressure, cor-

rosive fluids or high velocity. Additionally,

the use of a thermowell permits instrument

interchange or calibration check without

disturbing or closing down the process.

Ashcroft temperature switches have

bulb diameters to match

⁄8˝ nominal bore

thermowells. The bulbs have a sensitive

portion length of 2˝ which can be used

with 2

⁄2˝ “U” dimensioned thermowells or

longer. For maximum accuracy, a thermo-

well’s “U” dimension should be selected

to permit complete immersion of the sen-

sitive portion plus 1˝ when measuring the

temperature of liquids; an extra 3˝ should

be allowed when measuring the temper-

ature of gases.

Thermowell bushings should be used

with remote mount temperature switches.

We recommend the standard 3˝ bulb and

code 69 Series bushings for use with any

thermowell “U” dimension. A split rubber

grommet allows easy installation and “S”

dimension adjustment.

B-Series Switches – Pressure, Differential Pressure, Temperature & Hydraulic FEATURES B-Series switches have proven reliable in such harsh environments as: • Offshore oil rigs • Chemical and petrochemical plants • Pulp and paper mills • Steel mills • Power plants • Water and sewage-treatment plants • Other corrosive environments Ashcroft Inc. supplies highly reliable Ashcroft® switches and controls for industrial and process applications.
PAGE 2
B-Series Switches – Pressure, Differential Pressure, Temperature & Hydraulic Temperature Switches B-Series temperature switches feature a SAMA Class II vapor pressure thermal system. This system provides quick, accurate response to process temperature changes with negligible ambient temperature effects. This is inherent in the design due to the precise relation- ship that exists between temperature and pressure according to the vapor pressure laws.
PAGE 3
B-Series Switches – Pressure, Differential Pressure, Temperature & Hydraulic Pressure & Differential Pressure Switches B-Series pressure, differential pressure and vacuum switches use two different actuators depending on setpoint require-ments. For setpoints between 2 and 3000 psi, the simple, rugged diaphragm-sealed piston actuator is used. This design features high reliability and choice of actuator seal materials for virtually every application.
