Hygienic optical sensor measures dissolved oxygen
The Memosens COS81 D hygienic optical sensor (photo) measures dissolved oxygen in fermenters and bioreactors that are used in the food, pharmaceutical and biotechnology industries, and in drinking water and boiler-feedwater applications, as well. It can be used in all measuring points, from laboratory fermenters to production processes. This device measures dissolved oxygen, gaseous oxygen and temperature, with an accuracy to ±0.2%, says the company. It works in process temperatures from 15 to 280° F, and pressures from 0 to 1 90 psi. The compact stainless-steel sensor meets EHEDG (Type EL Class 1) and ASME BPE (including USP Class VI and FDA conformity) hygienic requirements to avoid product contamination. It also meets the requirements of GMP and GLP, and is designed to withstand clean-in-place and steam-in-place procedures, according to the manufacturer. - Endress+Hauser, Greenwood Ind.

Optical transducers provide dynamic torque measurement
The digital ORT 230/240 Series optical rotary torque sensors (photo) provide precise, dynamic measurement of rotary and static torque of less than 1 00 Nm, for bandwidths of up to 50 kHz. These new devices replace the company's E200 ORT Series, and feature advanced electronics that deliver improvements in resolution, frequency response, reduced current consumption and faster digital data throughput, says the manufacturer. Non-contact operation is said to ensure a long, reliable life with high accuracy and noise immunity, and the company offers a lifetime warranty. These sensors include self-diagnostics that report when the transducer's torque, speed ratings or calibration data have been exceeded. Additional sensors monitor shafttemperature for improved compensation and accuracy. Integral software enables data display and recording. - Sensor Technology Ltd. Banbury, U.K.

Piezoresistive pressure sensor has a tiny footprint
The Micropressure MPR Series pressure sensor is a small, piezorestive silicon device. The sensor has a package footrpint of just 5-by-5 mm (0.20- by-0.20 in.), and it measures pressure from 0.6 to 30 psi, over a compensated temperature range of 32-1 22°F. It is fully calibrated and compensated to provide digital output, and is easy to implement into a range of end products. The device is compatible with a variety of liquid media, making it suitable for applications such as liquidlevel measurement, and is available with a food-grade or medical-grade gel for applications...
