Installation Procedure:
The Intrinsic Safety Control Drawing INS10012 (attached) shows the installation
requirements for CTC IS Sensors. As shown, properly installed barriers are
required to limit the energy the sensor can receive. Cabling brings the signal
from the sensor to the Zener diode barrier or galvanic isolator, which is the
energy-limiting interface. The signal is transferred through the barrier (which can
be located in a Class I Div 2 or non-hazardous area to measurement equipment,
such as a data collector or junction box) for further processing.
Standards
Each sensor that is approved for IS must meet or exceed the requirements for
standards recognized by the countries that would use the sensors.
Specific Conditions of Use:
1. Specific Ambient Conditions of Use include:
a. -40 C to 80 C for all LP series & AC91X series sensors (T4).
b. -54 C to 125 C for all AC90X series sensors (T3).
c. -40 C to 125 C for all AC91X series sensors (T3).
Special Conditions for safe use:
None
