n NORMAL OPERATING CONDITIONS

Ambient Temperature:

General-purpose Use:

–40 to +55°C (–40 to +131°F)

Explosion proof type:

In the case of explosion proof type, refer to de-

scription of “ Ambient Temperature” “Enclosure” in

“HAZARDOUS AREA CLASSIFICATION”

*1: Minimum temperature should also be limited according

tominimumuidtemperatureofowtube’sspecica-

tion.

Refer to description of “Fluid Temperature and Pressure”.

*2: Indicator operating range: –20 to +55°C (–4 to +131°F)

Ambient Humidity: 0 to 100%

Lengthy continuous operation at 95% or more is not

recommended.

Vibration Conditions:

9.8 m/s

or less (frequency of 500 Hz or less)

Note: · Level of vibration is in conformity with IEC 60068-2-6

(SAMA 31.1-1980).

· Avoid locations with much vibration where the pipe

vibration frequency is 500 Hz or more. Such a condi-

tion may cause damage to the instrument.
