Fischer DS1106VA22B10W00 Differential Pressure Switch
Working principle:
Mechanical differential pressure sensor, detects the pressure difference of gas/liquid through diaphragm or piston, triggers micro switch (SPDT or DPDT contact).
Optional electronic type (with digital display and signal output, need to confirm the model suffix).
Range:
Differential pressure range: estimated to be 0...6 kPa (or custom range, need to be decoded according to DS1106 part).
Maximum static pressure: typical value 16 bar
Output signal:
Single pole double throw (SPDT) relay, contact capacity is usually 5A/250V AC (or 2A/30V DC).
Optional 4-20mA analog output or PNP/NPN transistor output (electronic model).
Material and structure:
Wetted parts: 316L stainless steel (corrosion resistant), fluororubber seal (compatible with oil, water, air).
Casing: aluminum alloy (protection grade IP65) or plastic (lightweight application).
Process connection: G1/4" internal thread
Adjustment and display:
Adjustable set point: Adjust by knob or screwdriver, covering 20%~100% of the range.
Mechanical dial or LED digital display (supported by some models).
Environmental adaptability:
Media temperature: -20°C ~ +80°C (high temperature type can reach +120°C, special seal required).
Ambient temperature: -40°C ~ +85°C.
Explosion-proof certification: ATEX/IECEx optional (for hazardous areas).
