The Watson Smith Type 140 current to pressure (I/P) convertor exceeds the requirements of process control industry applications worldwide.
The Watson Smith Type 140 current to pressure (I/P) convertor exceeds the requirements of process control industry applications worldwide.
The Type 140 design has been based on an analysis of the key requirements and applications for this class of product in all major international markets.
Delivering advantage both in terms of safety and performance the features include: fail to zero output pressure on signal failure; advanced electronic closed loop, giving extreme control precision; rugged, IP66 housing to meet the most demanding environmental conditions; vibration immunity; and extensive operating temperature range from -40 +85C.
These features make the Type 140 suitable to a variety of mounting positions and locations.
The Type 140 has comprehensive hazardous area certification.
Approvals include North American, Canadian and European ATEX certification, encompassing intrinsically safe, type N and flameproof variants.
An additional user feature is the inclusion of a jack socket for on site monitoring and local calibration, thus ensuring maximum operational uptime.
The Type 140 has been designed with reliability in mind.
Encapsulated modular electronics and a submicron field-replaceable pilot air filter give an order of magnitude in reliability improvement.
Through engineering advantage, this addition to the Watson Smith range, gives the user a trouble-free fit-and-forget current to pressure convertor.
The unit is available in pressure ratings in the range 0.2 to 1.0bar with a flow capacity exceeding 300 litre/min.
