Operating Influences
Supply Pressure Sensitivity: A 10% change in
supply pressure changes the valve shaft position
less than the following percentages of valve
rotation:
Type 3710: 1.0% at 4.1 bar (60 psig) supply
pressure
Type 3720: 1.5% at 4.1 bar (60 psig) supply
pressure
Operative Temperature Limits
J −40 to 80_C (−40 to 180_F), J −50 to 80_C
(−58 to 180_F) or J 0 to 107_C (32 to 225_F)
(Type 3710 only)
Hazardous Area Classification for Type 3710
Type 3710 pneumatic positioners comply with the
requirements of ATEX Group II Category 2 Gas
and Dust
Housing Classification for Type 3722 Converter
NEMA 3 (FM), Enclosure 3 (CSA), IP54 per IEC
60529. Mount instrument with vent on side or
bottom if weatherproofing is a concern.
1. This term is defined in ISA Standard S51.1.
2. For direct action, an increasing input signal extends actuator rod. For reverse action, an increasing input signal retracts actuator rod.
3. Normal cubic meters per hour (0°C and 1.01325 bar absolute). Scfh — standard cubic feet per hour (60°F and 14.7 psia).
4. Typical valves tested using a Fisher Type 1061 size 30 actuator at 4.1 bar (60 psig) supply pressure. Performance may vary with other actuator types and supply pressures.
5. The pressure and temperature limits in the document, and any applicable code or standard limitation should not be exceeded.
