Fathom Systems iVPs are likely to feature a number of internal pressure transducers. In addition to those previously mentioned in the NG3 Module section which may feature as an integral fit to a PRV, other transducers are offered as part of the system make-up. A standard sandwich mount block of similar envelope to the NG3 PO check valve is fitted to the underside of the directional control valve and with either 1 or 2 transducers fitted. As standard, a system depth measurement transducer features with the option of a 2nd transducer being installed as a means of measuring hydraulic system pressure. This 2nd transducer may not be required if a PRV module features. A variant of this is the offer of the same sandwich mount block with 2 transducers fitted specifically to measure the service line pressure from both the A and B ports of a particular bi-directional valve.
