Becker PS-2 Series
Description:
The Becker PS-2 Series Non-Bleed
Pressure Sensors shutoff bleed gas from �seat & nozzle type� double
acting instrumentation when the control valve is in the full open and/or
full closed position. Monitor regulators and standby regulators are typically
equipped with Non Bleed Sensors in order to reduce bleed gas emissions.
For zero bleed at both full open and full closed position, two (2) PS
Non-bleed Sensors are required.
The PS is the secondary choice
for Non-Bleed technology and should be used be utilized only in applications
where the NBV will not function such as when the primary control
instrumentation must discharge to high pressure systems. PDischarge>60
psig.

| Benefits:
Compatibility:
PS-2 Non-Bleed Sensors are
compatible with the following Becker double acting instrumentation:
- VRP-Model Pilots
- HPP-2 Model Positioners
- HPP-2E Model Positioners
Note that Becker
single-acting instrumentation do NOT utilize Non-Bleed Sensors.
Models Available:
|
Features:
-
Rugged
anodized aircraft aluminum and stainless steel construction provides
ultimate reliability and accuracy without affecting normal operation
of control instrumentation
-
Setpoint
can be set up anywhere within the control range of the unit. Seven
control springs are available for varying control ranges (See Table
3).
-
Supply
pressure up to 600 psig
- Stainless steel option
available
Usage:
PS-2 Non-Bleed Sensors are
typically used when double-acting control valves remain in a full open
and/or full closed position such as monitor or standby regulators.
PS-2 Sensors are utilized
when the following conditions exist:
- Psupply >
150 psig
- Psupply <
75 psig
- Pdischarge >
60 psig
Becker single-acting
equipment do NOT utilize Non-Bleed Sensors
