M23-M33-M43-M63 Pressure gauges with electrical contacts intrinsically safe version M23/M33 - Differential pressure M43 - Relative pressure with strong overpressure M63 - Pression Absolue Gauges with bellows Ø 150 mm For corrosive fluids and atmospheres Inductive contacts Conform to ATEX 94/9/CE (EN 60079-0/EN 60079-11) LCIE 03 ATEX 6402X CE 0081 II 2 G Ex ia IIA T6 or T5 or T4 Gb Hazardous area: 1 and 2 Based upon the MZ (M23) - MX (M33) - ME (M43) - MA (M63) gauges of which they share all caractheristics, they are fitted with inductive electrical contacts. They may be used in working conditions under vibrations. Specifications (20°C) Measurement range See table on next page Accuracy ±3% Block diagram showing the contact block control functions: For each independent inductive contact : U nominal 8 Vdc - electrical consumption ≥ 3mA - Ci = 30 nF, Li = 100 uH Gauge working -20...70°C for SJ2N cell temperature -40...70°C for SJ2SN cell Classification in temperature T4-T6 of inductive contacts, see data sheet A21.33. Every precaution must be taken by the user to ensure that the heat transfer by the fluid to the unit head does not raise the unit head temperature to the spontaneous ignition temperature of the gas in which it is situated. Protection rating IP 65 according NF EN 60529. Sensing elementTwo 1.4404 (AISI 316L) stainless steel bellows.
