Neodyn 130P Series Pressure Switch / Tamper ResistantIndonesia Industrial Parts

Descriptions of Neodyn 130P Series Pressure Switch / Tamper Resistant

Neodyn 130P Series Pressure Switch / Tamper Resistant for hazardous or corrosive atmospheres. For low to mid-range pressure applications. Features efficient Nega-Rate® Belleville disc spring for superior set point stability and is field adjustable using a 1/8? Allen wrench through the port.

Once adjustments are made and the switch is installed, it becomes tamper-proof.

No moving parts except during actuation—no spring fatigue or wear.
The set point is mostly a function of the negative rate Belleville spring—variables in snap action electrical have little effect on the set point.
Total movement of the Belleville spring compensates for any relocation of the electrical due to case growth—consistent set point over temperature change.
No linkage utilized—no wear which can affect accuracy.

Features

Stable Set Points – “Eliminates Constant Recalibration”

No moving parts except during actuation—no spring fatigue or wear.
Set point is mostly a function of the negative rate Belleville spring—variables in snap action electrical have little effect on the set point.
Total movement of the Belleville spring compensates for any relocation of the electrical due to case growth—consistent set point over temperature change.
No linkage utilized—no wear which can affect accuracy.

Vibration Resistant – “Eliminates Contact Chatter”

Belleville spring does not preload the electrical prior to actuation—snap action electrical maintains its vibration resistant characteristic.
Small mass and inherent stability of the Belleville spring resists chatter caused by vibration.
Snap action electrical is ruggedly mounted with minimal bracketry—no spring mounted electricals or linkages.

High Over-Pressure Capability – “No Affect on Set Point Accuracy”

Belleville spring does not contain the pressure—no affect on system or proof pressure capability.
The pressure sensing portion bottoms out after actuation and is fully supported—pressure sensing parts are designed for high pressure conditions.
Limited movement of spring mechanism—no overtravel of the snap action electrical due to high pressure.

High Cycle Lifer – “Millions of Cycle”

Short stroke minimizes wear—Belleville spring mechanism is exercised less than .020?.
Snap action of Belleville spring reduces electrical arc—prolongs contact life.
