PRESSURE SWITCHES PRESSURE SWITCHES Enclosures: Cast Aluminum: Oven baked powder coating hammertone grey Also available in SS 316 Wheaterproof IP 66 EN 60529 (Nema 4X) Standard unit: Barg Optional: PSI / Kg / Pa Standard process connetion: 1/4” NPT F or BSP F RANGES for Differential switches RANGE CODE Standard Diaghragm/O-ring: D..L/ M: Buna N / Buna N D..H: TCP/ Buna N For wetted parts: more possibilities available, see full catalogue ADJUSTABLE RANGE 1 DIFF. RANGE ) mBar / Bar TYPICAL DEADBAND PROOF PRESSURE Tutti i dati ed i contenuti di questa scheda sono di proprietà esclusiva di Riels Instruments Repeatablity: typical 0.2% of Full Scale ) Ranges and deadbands are given at 50% of Max. Static pressure. All differential pressure sensors are sensitive to static pressure, both for setpoint and deadband. 2 ) Range only with L1 micro switch. 3 ) D…L can withstand a differential pressure P-low max. 1 bar above P-High. 4 ) D…M, D…H can sustain full High and Low-side reversal. 1 IN THE FOLLOWING TABLE THE ESTIMATED INFLUENCE FOR INCREASING STATIC PRESSURE IS GIVEN. Example: D…H-type Diff. setpoint: 1 bar (1000 mbar). If static pressure increases 10 bar Diff.setpoint will be (10 x – 2 mbar ) = - 20 mbar less = 980 mbar.
