Instrumentation
The EnPro PI-1 Controller has been developed to provide a pulse output signal proportional to a pneu- matic input signal i.e. 20 – 100 kPa.
Typical uses are composite sample extraction for pipelines and ship loading and unloading.
The unit is entirely pneumatic and therefore poses no hazardous area or electrical supply concerns.
The EnPro range of pneumatic timers have been de- veloped to satisfy the need for small portable, accur- ate pneumatic timers, that will actuate samplers or valves in hazardous environments where protected electrical/electronic devices present problems with complexity and weight.
