Dimensions of the indicator

Internal tube type

Approx. mass: 1.1 kg

Fluid temperature: 0 to 149°C

External tube type

Approx. mass: 1.2 kg

Fluid temperature: -20 to 200°C

● Local indication + electric transmitter

● Local indication + electric transmitter + HART communication

Power supply voltage

: 10 to 30 V DC between transmitter terminals

10 to 28V DC for intrinsically safe circuits

Current output

: 4 to 20 mA DC

Effective output range from 4.0 to 21.6 mA, or 22.8 mA under abnormal conditions (3.75 mA also available as an

option)

Allowable load resistance

: 830

Ω or less for electric transmitter (580Ω or less/24 V DC)

230 to 830

Ω for electric transmitter + HART communication

(Load resistance of 230

Ω or more is required for HART communication.)

The allowable load resistance for each power supply voltage can be determined by following formula:

Allowable load resistance

≤ (power supply voltage [V] − 10)/0.024 [Ω] (including the resistance value for the

circuit wiring)

Output accuracy

:

±1.0% F.S. (against the flow scale)

Temperature change effect : 10

μA/°C

Low cut off

: 0 to 20% (7% F.S. by default)

Damping

: 0 to 20s (1s by default)

Cable entry

: Non-explosion-proof / intrinsic safety : M20

×1.5, G1/2, NPT1/2, water-proof connector

Flameproof

: M20

×1.5, NPT1/2, packing type cable gland

Note: Use the EXPC-16B flameproof cable gland by Shimada Electric Co. for the TIIS-certified flameproof type.
