Sensor small but perfectly formed

Penny & Giles claims to have made the world’s smallest linear position sensor with the launch of its VRVT 050 which has a body diameter of 5mm and a body-to-stroke ratio of 1.2:1. The device is an in-cylinder position sensor for installation in smaller bore actuators where space is at a premium. Its threaded core configuration and sub-miniature body size simplifies installation and minimises machining costs.

Compact dimensions also make the VRVT 050 suitable for retrofitting to cylinders which could otherwise fit only external devices.

The SEM 210 smart in-head temperature transmitter from Status Instruments accepts any commonly used temperature sensor, slidewire transducer or millivolt signal and converts the output to the industry standard 4-20mA. The unit is easily programmed for sensor type and range.

A software package running under Windows on a PC communicates via an interface adapter down the same pair of wires that carry the 4-20mA output signal which enables re-programming or interrogation while the transmitter is connected in an existing loop.

The Solartron Linear Encoder is for use in any application where a high level of accuracy is required, such as measuring first-off precision machined components in a standards room or the calibration of standards and gauges.

The linear encoder can also be used to determine the position of moving parts such as X-Y tables on a microscope in a laboratory environment. There are two stroke lengths of 12mm and 25mm with 50mm and 100mm stroke probes to be launched later this year. The encoders are operated by a standard spring return or they can be activated remotely by a cable lift.
