Tubular Solenoids

A series of 1.250-in. diameter tubular solenoids has been released by Magnetic Sensor Systems (MSS), Van Nuys, CA. Ideal for strokes of up to 1.00 in., the S-20-125 series of pull type tubular solenoids features 18 different solenoids with 23 to 40 AWG (American Wire Gauge) windings. The solenoids feature a 1.25 in. diameter × 2.00 in. long housing and a 3/4-18 mounting thread. The noncaptive plunger, made of low residual magnetic steel for quick release, has a diameter of 0.437 in. with a clevis end for load attachment. A low friction brass guide and PTFE coating on the plunger ensures long life.

Flow Sensor

PSG Biotech, Oakbrook Terrace, IL, has launched updated flow sensors and flow measurement technologies to ensure maximum media-integrity protection. The BioProTT™ FlowSU System is designed for single-use biopharma applications. It eliminates the need for calibration and can be easily integrated into most standard manifolds while performing flow-measurement and air-in-line detection tasks simultaneously. The sensor’s straight-line flow path also produces product transfer with less shear stress to better protect sensitive fluids from damage. The SumoFlo^® CPFM-8103 Single-Use Coriolis Mass Flow Meter has been updated for upstream, laboratory, and cell and gene therapy applications. It is now available with both inlet and outlet ports. A new ¼ in. connection is available.
