Transmitters have always been the most popular choice for pressure measurement applications, because of their accuracy, reliability and direct communication with a PLC or DCS.
The drawback to a transmitter is the price.
They are not the cheapest instrument: the clever buyer knows when a transmitter is actually required, and whether a cost effective alternative can be used.
Routine is another aspect that is difficult to overcome.
If you have service and maintenance agreements for pressure transmitters say, it feels difficult to change tradition and actually use the cost effective alternative of a pressure switch.
The One Series, a 2-wire range of switches, now offer a cost saving alternative to transmitters with all the benefits for those applications where a transmitter is just not needed.
Our new range of switches offer our customers a real opportunity to get out of that 'locked in' position.
The major facts, apart from the savings in cost, are as follows.
The ONE series.
Is a 2 wire device which receives power and signals the switching over the same two wires.
Attaches directly to the standard inputs of a PLC or DCS with no additional wiring.
Is an economical alternative to costly transmitters with all the benefits you need.
Includes health diagnostics as standard - you know that your switch is working via the local display or remotely with a signal.
Has no moving parts, and has a local display.
Can simultaneously provide a local switch signal and the health status signal.
Replaces 3 instruments - a switch, a gauge and a transmitter in one unit.
Has ATEX Approvals.
