Description
P233A Series Sensitive (Differential) Pressure Switch for Air - SPDT switch for sensing air flow, single or differential air pressure.
This (differential) pressure switch is used to sense flow of air, single or differential air pressure.
This switch senses a change in the (differential) pressure (either velocity pressure or pressure drop across a restriction) as the airflow changes. The (differential) pressure is applied to the two sides of a diaphragm in the control. The spring-loaded diaphragm moves and actuates the switch. The series P233A/F can also be used to detect small positive gauge pressure by using only the high-pressure connection and leaving the low-pressure port open, or to detect a vacuum by using only the low pressure connection and leaving the high-pressure port open to ambient pressure.
Features and Benefits
* One switch to measure relative pressure, vacuum or differential pressure - provides versatility to match various applications
* Various accessories available - provides flexibility
* Compact and durable construction - provides durability in combination with neutral gases
* Easy mounting and wiring, various mounting possibilities - reduce installation time
* Standard PG 11 nipple and optional DIN 43650 connector - provides flexibility in wiring connections
* Accurate and stable switch point - provides high accuracy and repeatability
* SPDT contact standard - can be used for "normally open" or "normally closed" applications
Typical Applications
* Detect clogged filter
* Detect frost or ice build-up on air conditioning coils
* Air proving in heating or ventilation ducts
* Maximum airflow controller for variable air volume system
* Detect blocked flue or vent
* Monitor fan operation
Adjustment (OEM)
The scale values indicate the approximate switching point at increasing pressure (contacts 3-1 to open). If accurate setting is required, the approximate setting on the scale should be corrected by using a pressure gauge. Select a mounting location where vibrations are minimal; the control is calibrated with the diaphragm vertical. Repair is not possible - in case of a defective or improperly functioning control, replace it.
