Manostat 1/4″ precision regulator
The Manostat 1/4″ precision regulator is the mainstay of the Watson Smith range. This unit comes with hand wheel operation as standard with options for integral pressure gauge and lever or plunger operation without a gauge. Based on the Manostat regulator, the 100X gives direct electrical control of the output pressure by a 4-20mA or 1-10V signal and is a very popular and cost effective unit. Also available ATEX approved. The 140 series expands on the I/P control concept by providing a unit that has a very high accuracy, is immune from vibration and has the distinction of being the only ATEX triple certified I/P available covering EBenX, Axed and Exeo for zones 0, 1 and2. This unit is also readily serviced in the field as the electronics can be swapped without removing the air supply.

The 422 series offers a totally unique function for I/P converters in that it has a Fail Freeze operation allowing the pressure to be maintained in the event of power failure. Vibration immune, it is also ATEXapproved to EBenX and Exeo.
