How far can I remote mount a catalytic bead sensor from the S4000C's electronics?
The maximum distance the catalytic bead sensor can be remote mounted from the S4000C's electronics is 7600 ft. (2320 m) using a three-conductor 14 AWG shielded cable/wire. For remote mounting applications, you will require the explosion-proof sensor junction box part number 10252-1. Contact your local representative or factory for additional accessories and assistance.

How often should I calibrate my combustible gas sensors?
We recommend that all combustible gas detectors be calibrated at least once every 90 days to ensure integrity. We are not implying that the sensor will drift or have problems within this period but frequent calibration checks merely ensure the integrity and operation of the life protecting equipment.

This should be used as a guideline only and in some applications more frequent calibrations may be required. Each application must be carefully evaluated to determine the frequency of calibration.

Catalytic Bead
What is your typical catalytic bead sensor life?
We state 3-5 years in our literature but we have seen sensors last over 10 years and still function properly. It really depends on the application.

What gas is used to calibrate your catalytic sensors?
We normally use 50% LEL of the target gas. The calibration kits consist of a bottle of gas, .45 liter / min regulator, tubing and calibration cup.

Point Infrared
Can I remote mount and remote calibrate the IR2100?
The IR2100 can be remote mounted from the FMD field mounted display. The IR2100 can be remote tested for response operation. It can be remote zeroed but cannot be remote calibrated due to air currents around the sensor. A calibration cup will have to be placed over the sensor head for span calibration.

What is the expected life expectancy of the IR2100?
Since poisons will not affect the IR2100, customers should expect 10 years of life.

Will fog prevent the IR2100 from working properly?
No. We also have rain shields to prevent heavy rains from blocking the IR beams.

Open-Path Infrared
Will the IR5000 tell me where the gas leak is along its path of detection?
No. The IR5000 lets you know that there is a leak somewhere between the IR5000 source and receiver. Only point detectors such as the IR2100 or S4000C will tell you more information as to the leak location.

Can I use the same unit to detect a methane gas leak and a propane gas leak?
No. Because of the bond structure of the heavy gases you must use a IR5000 which is programmed different than the unit for methane.

How do you calibrate the IR5000?
The IR5000 is calibrated at the factory. The unit can be re-zeroed but does not need to be recalibrated in the field. We use a set of films to check the operation of the unit. This is typical of all open path gas detectors.
