o Scale ranges for pressure values between 16 mbar and 25 bar:
- see table C1 at page P04; (divisions as per table C1 at page P04).
- other graduations not normalized for single or double range (on request).
o Unit of pressure:
- mbar, bar, kPa, kg/cm2 and psi for single or double range.
o Scale angle:
- 270 °.
nota: scale angle is 180° with ranges 0 ÷ 25 mbar for model DP 460 and 0 ÷ 100 mbar for model DP 360.
• Pointer
- aluminium with micrometer adjustment.
• Dial
- white aluminium with black figures (for dial modifications see available options).
• Accuracy (according EN 837)
- classe1,6 (± 1,6% of full scale deflection).).
note1: accuracy indicated on the pressure gauge does not consider the interference of an eventually applied electric contact.
note2: diaphragm seal can affect instrument accuracy according with the service conditions because of the pressure/temperature ratio.
• Ambient temperature
- -30 ÷ +60 °C.
• Operating temperature
- max 120 °C.
• Thermal drift
- with reference to the ambient temperature of 20°C, hermal drift affects the instrument accuracy as ± 0,6% every 10°C of variations.
