ΤΕΧΝΙΚΑ ΧΑΡΑΚΤΗΡΙΣΤΙΚΑ
• Nominal sizes
- 100 and 150.
• Models
- MA 325: ranges included between 0,6 and 2,5 bar absolute;
- MA 425: ranges included between 25 and 400 mbar absolute;
• Casing
- case and ring in AISI 304 stainless steel (AISI 316 on request - option V61) with bayonet bezel.
• Protection degree (according to EN 60529)
- IP 55 standard - dry execution;
- IP 65 not fillable (option V72).
• Window
- glass;
- laminated safety glass (on request - option V17).
• Blow out device
- blow out plug.
• Pressure connection (according to EN 837)
AISI 316L stainless steel threaded G 1/2 B (1/2 Gas or BSP) or 1/2-14 NPT EXT (1/2 NPT).
• Pressure element
- AISI 316Ti stainless steel diaphragm.
• Movement
- stainless steel.
• Ranges (according to EN 837)
o Scale ranges
for pressure values between 25 mbar and 2,5 bar abs:
- see table B1 at page P06; (divisions as per table C1 at page P08);
- 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 ° (180 ° for range 0÷25 mbar).
• Pointer
- aluminium with micrometer adjustment.
• Dial
- white aluminium with black figures (for dial modifications see available options).
• Accuracy (according to EN 837)
- class 1,6 (± 1,6% of full scale deflection).
note 1: accuracy class is not affected by atmospheric pressure changes.
note 2: accuracy indicated on the pressure gauge does not consider the interference of on eventually applied electric contact.
• Ambient temperature
- -20÷+60°C.
• Operating temperature
- max 120°C.
• Thermal drift
- out of the optimum ambient temperature values included within +15 ÷ +25°C, the thermal drift affects the instruments accuracy as follows:
- 0,3% every 10°C for model MA 325;
- 0,5% every 10°C for model MA 425.
