Installation Precautions Tighten/remove with wrench on hex fitting only. Do not attempt to rotate gauge by turning housing. Use fittings appropriate for the pressure range of the gauge. Do not apply vacuum to gauges not designed for vacuum operation. NEVER insert objects into the gauge port or blow out with compressed air. Permanent damage not covered by warranty will result to the sensor. The DPG1100AD and DPG1100ADBL can be powered by any AC source of 8 to 24 VAC 50/60 Hz, or any DC source of

GAUGE reference units may be re-zeroed without affecting the span calibration. The gauge port must be open to the ambient with no pressure or vacuum applied. Adjust the Zero control until the gauge reads zero with the minus (–) sign occasionally flashing. Span calibration should only be attempted if the user has access to a pressure reference of known accuracy. The accuracy of the calibration equipment should be at least four times the gauge accuracy. Zero calibration must be done before span ca

OMEGA’s WARRANTY adds an additional one (1) month grace period to the normal one (1) year product warranty to cover handling and shipping time. This ensures that OMEGA’s customers receive maximum coverage on each product. If the unit malfunctions, it must be returned to the factory for evaluation. OMEGA’s Customer Service Department will issue an Authorized Return (AR) number immediately upon phone or written request. Upon examination by OMEGA, if the unit is found to be defective, it will be re

• The conductors of the intrinsically safe circuit should be sealed in a rigid metal conduit at the point where the wiring enters the hazardous area. The wiring and sensor switch should be such that conductive dusts in the hazardous area will not close the circuit. • Hazardous area field wiring will store energy due to distributed capacitance and inductance in proportion to its length. It is therefore recommended that the characteristics of the cable be known and judged against the length of run

Failure to observe this warning could result in serious injuries or damages. GROUP CAPACITANCE INDUCTANCE A & B 0.1 .F 3 mH C 0.2 .F 10mH D 0.3 .F 20mH Example: Typical values of capacitance for a twisted pair of copper wires is between 20 and 60 pF per foot. Using the maximum value of 60pF/ft, Groups A & B could have a run of 1500+ feet with safety. Inductance of a typical twisted pair is between 0.10 and 0.20 .H/ ft, thus making a cable run in this example essentially determined by the capacit
