Compliance with the simple apparatus requirements
PH8EFP meet the simple apparatus requirements defined in the following standards.
Note: TIIS certified types cannot be connected.
Use the sensors under the conditions of use required by the standards.
Applicable standards:
ANSI/ISA-60079-11 (2014)
ANSI/ISA-60079-0 (2009)
CAN/CSA-C22.2 NO. 60079-11:14
CAN/CSA-C22.2 NO. 60079-0:11
방호장치 의무안전인증 고시
GB 3836.4-2010
Conditions of use:
(1) Use in combination with an internally isolated transmitter, or use with, a transmitter in
combination with isolated barrier.
The FLXA21 is internally isolated.
(2) Upper limit of the process temperature.
The upper limit of process temperature is indicated below when the sensor is used in
combination with a YOKOGAWA transmitter.
For FLXA21, model and suffix code below is available.
FLXA21-D-□-D-EA-P1-○-A-N-LA-N-NN
□ can be any value.
○ must be NN or P1.
Any option code is available.
For PH202S, model and suffix code below is available.
PH202S-○-E
○ must be C or U.
There are no PH202S models that meet the Korean explosion proof standards.
Any option code is available.
