B-Series Switches - Pressure, Differential Pressure, Temperature & Hydraulic B-Series switches have proven reliable in such harsh environments as: • 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 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- 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 Thermowells must be used on any appli- cation where the stem of the temperature 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 %" nominal bore thermowells. The bulbs have a sensitive portion length of 2" which can be used with 21/2""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- 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 Temperature Switches B-Series temperature switches feature a SAMA Class II vapor pressure thermal system. This system provides quick, accurate response to process tempera- ture 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. A wide selection of sensing bulb and armored capillary lengths is avail- able. The vapor pressure system design features small bulb sizes,...

B-Series Switches - Pressure, Differential Temperature & Hydraulic Pressure & Differential Pressure Switches B-Series pressure, differential pressure and vacuum switches use two different actuators depending on setpoint require-ments. For set- points 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. An optional welded design is also available for setpoints up to 1000 psi for All standard models feature ±1 percent of range setpoint repeatability and...
