Utilizing electrochemical sensor technology the Model 4101 provides accurate monitoring of hazardous gas conditions. Proven sensor design matched with reliable state-of-the-art electronics results in the ideal complete single channel package to protect your plant and personnel. Automatic Low Sensitivity Check Monitoring integrity is ensured with the automatic low sensitivity check. After calibration, a sensor sensivity check confirms that the sensor response to gas is sufficient to provide reliable operation without false indication. If the sensor has low sensitivity, an LED lights to indicate that sensor replacement is due. False Alarm Avoidance During Power-Up and Calibration, the transmitter output is locked at 4 mA. The output remains locked for five minutes directly after power is applied or after calibration gas is removed, allowing sufficient time to fully stabilize before coming on-line. This avoids erroneous readings during warm-up and prevents alarm caused by calibration gas. Convenient Diagnostic Measurements Critical measurements are made at convenient jacks for a Volt Ohm Meter. Each measurement location is clearly marked. All modules have a signal output adjustment. Model 4101 Series Gas Sensor Modules Simple Zero and Span Adjustments Easily accessible potentiometers enable calibration adjustments to be made in minutes by non-technical personnel for reduced maintenance cost. Flexible Alarm and Logging Options The analog gas sensor modules can be used as part of a facility gas risk management plan. The 4-20 mA output signal is ideally suited to interface with a wide range of instrumentation for alarm annunciation and recording. The sensor module is housed in a NEMA-7 enclosure rated for Class 1, Division 1, Groups C, D environments. An optional NEMA 4 Group B enclosure is available. Be sure to also look at the 5100-XX-IT Series Intelligent Gas Sensor Modules for network-enabled hazardous gas monitoring. 4101-16 - 22/27 Sierra Monitor Corp. 1991 Tarob Ct., Milpitas, CA 95035, USA, 408-262-6611, 800-727-4377, FAX: 408-262-9042Web Site: E-Mail: sales@sierramonitor.com Gas Sensor Modules Specifications Gas Type Model Sensor Std.
