Page 6: Description
Description This section describes the ppm hydrogen transmitter’s components. It is a 4 to 20 mA type detector head. It consists of the ppm hydrogen detector, amplifier, and junction box. Amplifier S PAN Locking Set Screw Reducing Bushing, J-Box 3/4 NPT to 1/2 NPT Hydrogen Detector Figure 1: Component Location PPM Hydrogen Detector... -
Page 7: Amplifier
Amplifier The amplifier converts the non-linear electrical output from the detector to a linear 4 to 20 mA signal that corresponds to the detection range and transmits the signal to a gas monitoring controller. The amplifier includes the terminal strips, span pot, linearizing pot, and test points. Controller Terminal Strip Detector Terminal Strip + Test Point, Red... -
Page 8: Junction Box
Test Points The test points are on the right side of the amplifier (see Figure 2). The test points produce a 100 to 500 mV output that corresponds to the transmitter’s 4 to 20 mA output. Use the test points and a voltmeter to measure the amplifier’s output during the start-up and calibration procedures. -

Page 10: Wiring The Ppm Hydrogen Transmitter
Wiring the PPM Hydrogen Transmitter WARNING: Always verify that the power to the controller is off before you make wiring connections. 1. Turn off power to the controller. 2. Place the controller’s power switch in the OFF position. 3. Remove the junction box cover. 4. - Page 11 Figure 4: Wiring the PPM Hydrogen Transmitter to a Controller 12. If shielded cable is used, connect the cable’s drain wire to an available chassis (earth) ground at the controller. RKI controllers typically have a ground stud that can be used to ground the cable’s drain wire.

Page 16: Calibration Frequency
Although there is no particular calibration frequency that is correct for all ppm hydrogen transmitter applications, a calibration frequency of every 6 to 12 months is adequate for most applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 6 months. -
