E0. Explanation of instrumentation and process control
General remarks
Design:
- Cast steel according ASTM A-216-WCC or WCB. Or equal to DIN;
- Stainless steel according ASTM A351-CF8M or CF8C. Or equal to DIN.
Without special notes the standard will be:
- Non Ex model and suitable for EEx(i) application;
- Sealing minimal IP65 according IEC/EN-60529;
- Transmitters signal output 4 -20 mA with HART protocol.
To compare pressure traps from PN into lbs ANSI-B use:
- PN 10 - 150 lbs;
- PN 16 - 150 lbs;
- PN 40 - 300 lbs;
- PN 100 - 600 lbs.
To compare pipe diameters DIN – ANSI use:
- DN15 - 0.5'';
- DN20 - 0.75'';
- DN25 - 1'';
- DN40 - 1.5'';
- DN50 - 2'';
- DN80 - 3'';
- DN100 - 4'';
- DN150 - 6'';
- DN200 - 8'';
- DN250 - 10''.
Variation
Quantum discount is possible. Special conditions like material and/or test certification are not included.
