Sierra Monitor : “Markets”


Sierra Monitor manufactures a wide variety of products designed to meet the needs of customers of all over the World.



Water and Wastewater Treatment

Waste water treatment facilities are located in every community and region. The process of treating the waste water requires the plant to utilizes a range of toxic and dangerous gases and the treatment process also produces toxic and combustible gases. In addition, there are many enclosed spaces in a waste water treatment plant where toxic gases can build up or non-toxic gases can deplete the oxygen making it dangerous to plant personnel.




Pharmaceutical plants utilize various toxic gases in the production of their product. Ethylene Oxide is used in sterilization of various pieces of equipment in the industry. Where the hazardous conditions are the greatest, it is necessary to have a plant wide monitoring system that can constantly monitor the conditions even if humans are not presently in the area so it is necessary to utilize fixed gas detection systems in addition to personal safety monitors. The Sentry Gas Detection System is designed for monitoring hazardous conditions and to provide the necessary information efficiently and in a comprehensive manner so that operators can quickly make decisions to protect the plant and personnel. The Field Server Gateway provides the interface necessary for safety devices, process equipment and facility controls.




Oil & Gas, Petrochemical and Chemical

Oil Refineries, petrochemical plants, LPG plants, offshore platforms and chemical plants all utilize or produce a wide range of hazardous gases including combustible gases and toxic gases. In addition, the processes could produce nontoxic gases which when accumulated in confined spaces, could deplete the oxygen deficient condition dangerous to individuals entering the area without proper protection. Where the hazardous conditions are the greatest, it is necessary to have a plant-wide monitoring system that can constantly monitor the conditions even if humans are not presently in the area. Personal gas monitors cannot detect build-up of combustible gases in a non-occupied area that could case a hazard to the facility. Depletion of oxygen would be hazardous to individuals entering the unoccupied area, and even small amounts of toxic gases can cause serious injury or death to workers entering an unoccupied area.


Sierra Monitor: “and Solutions”


Boiler rooms must be monitored for the critical hazards of combustible and toxic gas conditions. The key gases of concern are Combustible and Carbon Monoxide. In large installations which represent potential for hazardous conditions, it is necessary to utilize plant-wide monitoring systems that provide constant monitoring and data collection even when humans are not present. Personal gas monitors cannot detect build-up of combustible gases in a non occupied area that could cause a hazard to the facility.




Landfills, both closed and open landfills, generate combustible gas in the decomposition of the waste. Certain toxic gases can also be generated in this process. This combustible gas generation is of particular concern when buildings are put on top of a closed landfill or surrounding a closed or open landfill.



OEM Equipment manufacturers are faced with the choices every day of how to be able to link their device to the various systems found in product plants, buildings and other operations. Some industries have prevalent protocols used in interoperability, but most industries have various protocols, none of which is prevalent. In the process control industry users will find such protocols as Modbus, DF1, Profibus, ControlNet, Ethernet/IP, SNMP and others. In the building automation systems common protocols include LonWorks, BACnet, Metasys and Modbus. In addition, there is a full range of proprietary protocols that might be important to a particular device.


Sierra Monitor: Information Technology for Environment Measurement




LEVEL Products, Point & Continuous Measurements:

Measures a process by responding to a predefined range with a digital output, proportional 4-20mA or field bus signal.Ideal for liquid level or solids measurement.Models suitable for hazardous location are also available.




CorrTran MV, Corrosion Monitoring Transmitter:

A single product evaluates general & localized (pitting) corrosion & conductance. Provides a corrosion rate as a process control variable online & in real time. A wide range of process connections and probe configurations are available.




HMI Hazardous Solutions: Complete HMI solutions for a wide range of applications for pharmaceutical, food & beverage or cosmetics as well as other traditional process industries. Customized options include specialized keyboards, KVM extenders, GMP features, thin clients and unique mounting hardware.


VisuNet Remote Monitors are designed to communicate with Host PCs installed in remote locations by means of the Ethernet network. VisuNet Industrial monitors can be directly connected to the PC. The monitors come in several variants for use in hazardous and nonhazardous areas and in GMP conditions.


The Advanced Diagnostic Module monitors the field bus physical layer online and in real time. The Diagnostic Manager is the interface between personnel and field bus, and communicates with all diagnostic modules simultaneously. With the Diagnostic Manager’s software upgrade, guesswork is eliminated. Onsite work is reduced to a minimum and plant shutdowns are avoided.
