 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 

The Accelerometers Type 780A-IS, 786A-IS, 786F-IS, 786T-IS, 787A-IS, 787A-M8-IS, CMSS780A-IS, CMSS786A-IS, CMSS786F-IS, CMSS786T-IS, CMSS787A-IS and CMSS787A-M8-IS are used for vibration monitoring.
The sensor converts mechanical forces (e.g. vibrations) of the equipment to which it is mounted into an electrical signal and converts this into a modulated voltage output signal.
The accelerometers, types 786T-IS and CMSS786T-IS also measure the temperature of the equipment and convert this into a modulated voltage output signal.

Ambient temperature range -50 °C to +120 °C.

Supply and output circuit (power/signal and common):
in type of protection intrinsic safety Ex ia IIC, only for connection to a certified intrinsically safe circuit, with the following maximum values:
Ui = 28 V; Ii = 93 mA; Pi = 650 mW; Ci = See table below; Li = 0 mH.

For models 786T-IS and CMSS786T-IS:Supply and output circuits (power/signal, temperature sense and common):
in type of protection intrinsic safety Ex ia IIC, only for connection to a certified intrinsically safe circuit, with the following maximum values:
Ui = 28 V; Ii = 93 mA; Pi = 650 mW; Ci = See table below; Li = 0 mH.


 

780A-IS, 786A-IS, 787A-IS, 787A-M8-IS, CMSS780A-IS, CMSS786A-IS, CMSS787A-IS and CMSS787A-M8-IS786F-IS and CMSS786F-IS 786T-IS and CMSS786T-IS
Ci58 nF62 nF fixed cable included76 nF


 SPECIFIC CONDITIONS OF USE:   YES as shown below:
 
 
For applications in explosive atmospheres caused by gases, vapours or mists and where the use of apparatus with equipment protection level (EPL) Ga is required, electrostatic charges on the cable and non-metallic parts of the enclosure shall be avoided. The ambient temperature range for these applications is -40 °C to +80 °C.
