A Real Big Thing in the Cable

The most effective processing of sensor signals is done there where they arise - as close as possible to the sensor body itself. Therefore bursters now presents its in-line amplifier model 9235 integrated directly in the sensor feeds strain gauge bridges with resistances from 350 O to 1000 O and amplifies their singles to 0… 10 V. For its own supply a voltage of in between 15 V and 30 V is necessary. Thus, almost all sensors on strain gauge basis like load cells, pressures transducers and torque sensors can be connected within the wide range of 0.75 mV/V up to 2.5 mV/V. The cut-off frequency of the amplifier is designed for 1 kHz. By means of two sub-d-plugs the 75 g lightweight aluminium housing with its dimensions of only 62x55x16 mm can be connected at any given place within the cable. It goes without saying that the sensor supply is short-circuit-proof as well as the design of the amplifier supply prevents any pole confusion so that an additional safety for its installation is given. For OEM applications amplifier model 9235-V001 is available as an open circuit board that can easily be installed on existing controls panels. The technical data remains the same, only the electrical connection is realised by means of miniature plugs for open cable endings. Four bore-holes serve for its mechanical fixation.

Gange Of Ball Valves

Shreeram 182-HP is a series pf high pressure Ball Valves designed to suit wide range of applications, and pressures up to 500 Bar. The floating ball is held between pre-compressed seat for a leak-tight fit at both positive and negative pressures. The 182-HP features a blow-out-proof and glandless stem with a straight lever for smooth operation and better performance at high pressures. Gange of two valves mounted in one plate operated by one lever provides on and off together or one line can be off and another can be on at a time by one lever. These valves are available in 1/8" to 2" sizes with different end connections and materials to suit the customer's requirement. They can also be provided with locking arrangements.

Carbon Dioxide Sensor

The newly developed compact TGS4160 sensor is a hybrid sensor unit composed of carbon dioxide sensitive element and a thermistor. The CO2 sensitive element consists of a solid electrolyte formed between two electrodes, together with a printed heater substrate. By monitoring the change in electromotive force (emf) generated between the two electrodes, it is possible to measure CO2 gas concentration with high sensitivity. The Sensor exhibits long-term stability and shows excellent durability against the effects of high humidity and interfering gases through the application of innovative technology in the sensor's electrode design. The sensor is typically used as the basic sensing element of CO2 detectors used for air quality control especially in air-conditioned buildings and for fermentation process control. An optional microprocessor module AM-4 can be used to evaluate working of the sensor.
