Page 5: Introduction
Gas analysis takes place using thermal conductivity measurements made using a highly-stable, non-depleting katharometer sensor. The K1650 is supplied with zener barriers to provide an intrinsically safe interface between the sensor unit and the electronics allowing the sensor to be located in a hazardous area. -

3.3.3 Routing of wires To minimise the pick-up of electrical noise all signal wiring should be routed away from power cables. The K1650 is shipped with a pre-assembled sensor cable. See Section 4.7 for details. INM MTL 130-0126 Rev 13... -
Page 9: Sampling And Piping
Sampling and piping The connections are captive seal compression fittings suitable for 0.25” (or 6mm) diameter tube or double ferrule stainless steel compression fittings suitable for ” diameter tube on the sample inlet and sample outlet. NOTE Optimum analyser performance is achieved with the flow rate specified in Section 4.7 Consider also installing pipe work for a calibration gas inlet - this avoids the need to remove the sample connection when connecting a calibration gas. - Page 10 Range / Fault Alarm 120-0404-5 Connect to intrinsically safe earth M5 mounting studs (x 6) Cutout required at rear of panel in mounting surface 16mm length 186 x 138mm (centred) Figure 1 - Panel mounting dimensions (K1650) INM MTL 130-0126 Rev 13...

Page 16: Operation
NOTE During initialisation the K1650’s 4 to 20mA output goes to 2mA to indicate an invalid measurement. If the instrument is outside of its operating range (fault code displayed) then the 4 to 20mA output goes to 3.7mA to indicate this. The K6050, which has 0 to 1V analogue outputs, gives 0v during initialisation and 0V or 1V for fault conditions. -
Page 17: Making Measurements
Making measurements The sample flow rate should be set at 100-300 ml/min. It is essential that the range setting is appropriate to the measurement being made. The ranges are as follows • Range 1: 0 to 100% Carbon Dioxide in Air •... -

Page 19: Fault Codes
NOTE Hysteresis is the difference between the levels at which an alarm triggers and resets. For example, an instrument with a 100% range with an alarm set to mode = HIGH, level = 5% and hysteresis = 1% will trigger the alarm as the reading exceeds 5%, and reset it once the level has fallen to 4%. -
Page 20: Calibration
WARNING The analogue output is set to 2mA (K1650) or 0v (K6050) while the instrument is being calibrated. Ensure that any control loops that are connected to the instrument are disabled prior to verifying or calibrating the instrument. -
Page 21: Calibration Gases
Calibration gases Three are required. • 100% Hydrogen • 100% Carbon Dioxide • Dry Air The diagram that follows illustrates the calibration process. 5.3.1 Analysers working at alternator casing pressure When this is the case the analyser must be calibrated at the appropriate pressure(s) for best accuracy. -

Page 23: Servicing
The katharometer sensor is non-depleting and will last for a long time if it is not subjected to misuse. If a replacement is required, it must be returned to Eaton’s MTL product line, or their agent, because the sensor can only be replaced with the use of specialist equipment. - Page 24 MTL Instruments GmbH, Heinrich-Hertz-Str. 12, 50170 Kerpen, Germany UNITED ARAB EMIRATES Cooper Industries/Eaton Corporation Tel: +49 (0)22 73 98 12 - 0 Fax: +49 (0)22 73 98 12 - 2 00 Office 205/206, 2nd Floor SJ Towers, off.
