Validyne Engineering’s low to ultra-low differential pressure transducers and transmitters are available from Bestech Australia .
Designed for taking low pressure measurements, Validyne DR800 Draft Range pressure transmitters boast a ‘true’ full-scale range as low as ±0.25” H2O, making them perfect for air flow control applications. Featuring an adjustable scale of ±0.1” and ±100”, the DR800 offers 0.5% accuracy and operates between a temperature range of -290°C to +850°C .
Validyne’s DR800 Draft pressure sensors have simplified the zero and span adjustments and use a programmable circuit board jumper in unison with a 20-turn potentiometer to ensure the zero adjustment performs optimally. Adjusting the pot and jumper combination, ranges can be selected from -100% zero elevation to +85% zero suppression. The span adjust has a HI and LO gain jumper to support a better full-scale set point resolution, allowing for more turns from the potentiometer over a smaller percentage of the span and zero adjust range making the important set point calibrations simpler and much less time consuming.
The DR800 Draft pressure transmitter has an input range of 12 to 45VDC and protection for reverse polarity and short circuits. A true two-wire system, DR800 has a standard output of 4-20mA. The zero and span adjustment potentiometers are tamper-proof as they are protected by a cover plate.
The DR800 Draft Range pressure transmitter supplied by Bestech Australia has many excellent features, making it ideal for low pressure measurements.
