HSTA And HSTAR Sensors Resist Heat And Vibration Macro Sensors' HSTA and HSTAR LVDT-based linear-position sensors offer the environmental resistance and short-stroke sensor body length for cylinder applications where these are critical. While linear-position sensors were once considered too long for hydraulic applications, the development of new winding techniques, such as computerised layer winding and improved microprocessing, has considerably reduced the length of the linear-position sensor body compared with its measurable stroke length. In fact, for short-stroke actuators and cylinders (less than 6in), Macro Sensors' linear-position sensors can be much shorter than a magnetostrictive sensor. These linear-position sensors are hermetically sealed and AC-operated. They measure 3/4in (19mm) diameter and can survive in temperatures up to 200C and withstand high levels of shock and vibration. Coil windings are sealed against hostile environments to IEC standard IP-68. They a...

Tekscan has released the High-Temp Flexiforce Sensor HT201, which can measure forces in environments as hot as 200C. The ultra-thin, highly-linear (typically +/-1.2 per cent) High-Temp Flexiforce sensor is ideal for non-intrusive force measurement in a variety of processing applications, including injection moulding, heat sealing and heat-sink applications. Industries that will benefit from these high-temperature force measurements include automotive, aerospace, pharmaceutical, printing and food and drink processing. The sensor can: detect and measure a relative change in force or applied load; detect and measure the rate of change in force; identify force thresholds and trigger appropriate action; and detect contact and/or touch. The HT201 sensor is available in two force ranges, low and high.
