This table contains the dead band values for set point adjustment at 10% and 90% of the selected scale. For adjustable dead band the lower value corresponds to the dead band spring totally released and the higher corresponds to the dead band spring fully tensed. For other set points the dead band value can be calculated by linear interpolation between the values at 10% and 90%. 2015-11-12 1) Design and specifications subject to change without notice (*) For version with 2 microswitches lower values of the dead band must be multiplied x 1.5 (**) G1/4 female only www.baumer.com Data sheet A32.09 Page 3 / 5 RPPY4 Industrial pressure switch with intrinsic safety and high overpressure resistance Dimensions (mm) 125 76.5 = 144 139 = 58 130 5 64 100 45° Pressure range code: 151 - 152 - 153 - 154 Weight: 6.4 kg Hex 24 61 Ø 120 2015-11-12 Design and specifications subject to change without notice G 1/2(M) G 1/4 12 Ø 145 64 56 Ø 245 Hex 24 Hex 24 Hex 24 Hex 24 G 1/2(M) Pressure range code: 171 - 172 - 173 Weight: 7 kg 84 Pressure range code: 101 - 102 - 103 - 104 Weight: 10 kg www.baumer.com Data sheet A32.09 Page 4 / 5 RPPY4 Industrial pressure switch with intrinsic safety and high overpressure resistance Ordering details RPPY4 RP Model Industrial pressure switch Approvals ATEX intrinsic safety Sensing element Diaphragm (Viton ®), high overpressure resistance Type of micro switches 1 SPDT hermetically changeover switch 2 SPDT hermetically changeover switch 1 SPDT gold contact changeover switch 2 SPDT gold contact changeover switch 1 SPDT ultrasensitive gold contact changeover switch Process connection G 1/4 female (only pressure ranges 171, 172, 173) G 1/2 male (standard) 1/2 NPT male 1/4 NPT female Pressure range (mbar) Pressure range (kPa) -50 ... 0 -5 ... 0 -2 ... 10 -0.2 ... 1 -5 ... 50 -0.5 ... 5 -8 ... 100 -0.8 ... 10 -200... 0 -20 ... 0 0 ... 200 0 ... 20 0 ... 400 0 ... 40 0 ... 1000 0 ... 100 0 ... 700 0 ... 70 0 ... 1500 0 ... 150 0 ... 2500 0 ... 250 Options to be added behind the / (see example below) PY – 4 . xxx / RP PY – 4 Deadband Adjustable Adjustable Adjustable Adjustable Fix C W M K S H 3 6 8 . 101 102 103 104 151 152 153 154 171 172 173 Process connection G1/4 female Process connection G1/4 female Process connection G1/4 female / Ordering example with options RP PY – 4 C 3 . 101 / 0407 _ 9941 Industrial pressure switch With ATEX approval intrinsic safety Diaphragm Viton® 1 SPDT hermetically changeover switch Process connection G 1/2 male Design and specifications subject to change without notice Pressure range -50 ... 0 mbar Option: Mounting on 2" pipe 2015-11-12 Option: Stainless steel tag plate and wire www.baumer.com Data sheet A32.09 Page 5 / 5
