1. INTRODUCTION
This user manual (UM) is intended to describe design and operation of small-sized gas sensor
MIPEX-04-X-XX-3.1 (hereinafter MIPEX-04 or sensor). UM contains basic technical data,
recommendations and other information necessary for proper operation, maintenance and storage
of sensor.
Sensor is intended for automatic continuous measurement of hydrocarbons concentration in
atmosphere of hazardous areas. Sensor can be used as a part of gas-analyzing equipment groups
I and II according to IEC 60079-0 in the explosion-hazardous zones classes 0, 1, 2 according to IEC
60079-10-1, and Class I, Division 1, Group A, B, C, D according to UL Std. 913, CAN/CSA Std.
C22.2 No.157-92.
Any command stated in this UM as <X>, where X stands for a command text consisted of any
number of characters, must be read and/or sent without the symbols “<” and “>”.
SIA MIPEX reserves the right to make changes to this manual, excluding intrinsically
safe sensor parameters.
1.1. List of abbreviations
• LEL stands for Lower Explosive Limit;
• LED stands for Light Emitting Diode;
• CGM stands for Control Gas Mixture;
• NDIR stands for Non-Dispersive Infra-Red;
• UART stands for Universal Asynchronous Receiver/Transmitter.
• CRC stands for Cyclic Redundancy Check.
• IP stands for Ingress Protection.
• PCB stands for Printed Circuit Board.
1.2. List of terms
• Target gas is a gas, which sensor is intended to detect and measure its concentration.
• Calibration gas refers to CGM containing that gas, used for sensor calibration.
Any command stated in this UM as <X>, where X stands for a command text consisted of any
number of characters, must be read and/or sent without the symbols “<” and “>”.
