Very Low Range Dry/Dry Differential Pressure Transmitter | PrimAtu 10

At a Glance

Description

The PrimAtu 10 very low range dry/dry differential pressure transmitter is designed to measure the difference in pressure between non aggressive gases and then convert the pressure into a relative analogue electrical signal. The smallest pressure range that can be ordered is an incredibly low 0-0.3mbar. For whichever one of the six ranges you need, you will also have the choice between uni-directional or bi-directional measuring range direction. Bi-directional means that if you switch the highest pressure around you will see the positive pressure reading turn negative while uni-directional selection will just see the positive pressure reading fall to zero.

The PrimAtu 10 can be supplied with an optional built in 50mm x 15mm, 4-digit LCD pressure reading display and a digital MODBUS output. The pressure is measured by a piezoresistive silicon sensor and the sensor housing is constructed from PC-ABS V0 plastic. The PrimAtu 10 can be powered by a 24Vac or 24Vdc supply, or the optional 250Vac mains supply.

The standard PrimAtu 10 accuracy is ≤±1%/FSO and this can be upgraded to ≤±0.5%/FSO or to ≤±0.2/%/FSO* (*for ranges above 10mbar).

The PrimAtu 10 offers 6 ranges of pressure. See the PrimAtu10 datasheet for more details.

Need a differential pressure sensor with a higher measuring range? Try our wet wet differential pressure transmitter DMD331, that measures from 0-20mbar up to 0-16bar. The DMD331 is suitable for gases too.

Alternatively if you need higher accuracy then see our high accuracy low range differential pressure transmitter DPT100 which measures 0-10mbar up to 0-20,000mbar with an accuracy of up to ±0.1%/FSO.
