New improved silicon-chip differential pressure transducers

Keywords: Pressure sensors, Transducers

Autotran's unique series of low-cost, low pressure Differential and Gauge transducers are epitomised with the 860 series (Plate 5). For universal powering from AC or DC, output signals are either 1-5v DC or 1-6v DC or 1-10v DC or 4-20mA. These ISO-9001 certified units come in sturdy plastics cases with convenient mounting lugs and a screw terminal block.

The seven available ranges go down to 0.5inch H₂O and up to 40psi, media- compatible of the liquid variety, e.g.: humid air & water condensation e.g. in air ducts, ventilation pipes, and fan wells. Contrary to most transducers of this kind the Autotran 860 will operate below dewpoint without any degradation in performance.

Temperature-compensated from 10°C to 50°C these new transducers exhibit 1 per cent total error band accuracy and will operate from –25°C to +70°C.

Long term stability is better than 1 per cent of span; but for occasional resetting there is an offset adjustment (range up to 60 per cent of span).

With barbed pressure ports suitable for 1/8-inch tubing these 3in x 2.6in x 1.5in large units are available from EuroSensor. These transducers break new ground within the conbination of low-range, high-output, differential media compatibility, and low-cotst band at which the versatility sought for by the OEM has so long been denied.
