YJJ 1LEL 75C PM989-600A-CIT Electrochemical Combustible Gas Sensor

Product Description:

1LEL 75C PM989-600A-CIT Electrochemical Combustible Gas Sensor

Features:

The purpose of this document is to present the performance specification of the 1 LEL 75C Combustible Gas sensor.

This document should be used in conjunction with the 1 LEL 75 Characterisation Note, the Operating Principles (OP01), Instructions for Safe Use and the Product Safety Datasheet (PSDS 22).

The data provided in this document are valid at 20°C, 50% rH and 1013 mBar for 3 months from the date of sensor manufacture. For guidance on sensor performance outside of these limits, please refer to the 1 LEL 75 Characterisation Note.

Output signal can drift below the lower limit over time. For guidance on the safe use of the sensor, please refer to the Operating Principles OP01 and the Instructions for Safe Use.

Schedule of Limitations (Denoted by U After the Certificate Number)
• The sensors have been evaluated for a service temperature range of -40°C to +60°C.
• With regard to thermal ignition, the sensors have been evaluated as suitable for Group I use or for
Group II use with temperature code T4 for the stated service temperature range for Ui = 5 V.
• For group I applications with Ui > 5 V, the sensors must be installed in an enclosure preventing ingress
of coal dust.
• The device has not been assessed for resistance to impact or drop. The device shall be installed in a
suitably certified enclosure, per type of protection and in accordance with IEC 60079-0.
• The device has an external non-metallic surface greater the 400 mm2. It is therefore at risk of buildup
of electrostatic charge. The device shall be installed within an enclosure and limited to 400 mm2 of
material exposure.
• With regard to breather thermal temperature, including safety factor of 1.2 - breather surface
