详细说明
 Gas DetectionSierra Monitor Corporation, a public corporation (OTC: SRMC), designs, manufacturers and sells safety and environmental instrumentation. The company’s unique protocol translator product lines enable communication between disparate electronic systems overcoming protocol language barriers. By enabling communication between central building automation systems and many electronic subsystems, such as fire panels, chillers and air handlers, Sierra Monitor assists with the integration of energy saving systems. The company’s products improve the safety and comfort of workers while contributing to climate and natural resource protection. Sierra Monitor’s intelligent hazardous gas detection systems can be found in a broad range of applications including US Navy ships, wastewater treatment facilities, refineries, offshore oil platforms, chemical plants, parking garages and underground telephone vaults providing 24/7 protection of personnel and facilities. The four primary product groups are:
    Hazardous gas detection systems - used in a wide variety of industries, including chemical/petrochemical, wastewater treatment, transportation and oil and gas industries. Sierra Monitor is widely known as a technological leader in gas detection systems.
    Telecom Site Management Products - used by most telecommunications companies nationwide to monitor, manage and control HVAC, safety and security in remote environmental enclosures.
    FieldServer Technologies - protocol translator/gateways manufactured by the FieldServer Technologies division of Sierra Monitor providing the interoperability desired in the process control and building automation industries.
    ProtoCessor - protocol coprocessor from FieldServer Technologies is an OEM solution for product designers to incorporate an embedded solution to provide output to widely accepted protocols
With over 30 years of industry experience and more than 25,000 installations worldwide, Sierra Monitor is an industry leader in their fields:
    First to utilize a microprocessor-based controller for area safety monitoring.
    First to use digital two-way communication between the controller and the sensor for improved diagnostics, easy one-person calibration and multiplexing configuration.
    First to use Modbus serial communication to enable the hazardous gas detection system to link to the plant-wide DCS.
    First to provide the building automation industry with a universal protocol gateway supported by an extensive library of drivers for open systems and legacy devices
    First to provide the telecommunications industry with a comprehensive facilities environment controller
    First to provide a WebServer interface to a hazardous gas detection system


Gas Detectors & Gas Sensors
 
Single Channel Controllers
Gas sensor modules with a performance difference. Sierra Monitor gas sensor modules provide continuous trouble-free monitoring of hazardous gas conditions to protect your personnel and facility. Sierra Monitor integrates extensive gas sensor technology with electronics expertise to offer a broad line of diffusion gas sensor modules. The modules condition the sensor signal and provide an industry standard 4-20 mA output that can interface with single or multichannel controllers and distributed control systems. Sierra Monitor employs catalytic bead, electrochemical, semiconductor and infrared technologies to match the appropriate sensing technology with the application requirement.

Features provided on Sierra Monitor gas sensor modules include:
Reliability you can count on – Sensor design and electronic conditioning are carefully matched to maximize output signal integrity. All gas sensor modules are designed for hostile or hazardous environments and key sensors are FM approved.
Automatic low sensitivity check to ensure monitoring integrity – after calibration a sensor sensitivity check on many models confirms sufficient sensor response.
Convenient diagnostic measurements – the Sierra Monitor gas sensor modules provide the diagnostics necessary to ensure successful operation.
False alarm avoidance – during power-up and calibration on many models the output is logged at 4 mA to avoid erroneous readings.
Simple zero and span adjustments – featured on all Sierra Monitor gas sensor modules, using easily accessible potentiometers
