New calibration technology extends gas-detector operation
By Mary Page Bailey and Gerald Ondrey |
The new TruCal calibration technology, included with this company’s Ultima X5000 and General Monitors S5000 gas detectors (photo) for H2S and CO, means that the devices require no calibration checks for up to 24 months. Typically, a gas sensor’s electrolyte, or one or more of the electrodes, may limit the life of the sensor, especially in high-temperature or humid environments. These conditions and issues often require frequent recalibration or clearing of blocked sensors in harsh environments. The TruCal technology solves these problems with an extended calibration technology, which automatically self-checks and corrects sensor drift to extend calibration cycles using adaptive environmental-compensation (AEC) algorithms. This capability eliminates bump checks and assures the user that the sensor is healthy, measuring accurately and capable of detecting gas continuously. — MSA Safety, Cranberry Township, Pa.
