 Press Releases

  • A new fail-safe toxic gas detector that continually checks its electrochemical cell to give constant full-time protection has been announced by Minneapolis-based Sensor Electronics.

         Problem with a conventional toxic gas detector is that its electrochemical cell can suddenly die without warning – because the electrolyte evaporates or leaks, or a failed internal electrical connection.

         “Solution” has been to frequently bump test the cell, or periodically replace it.  Either method is costly, time-consuming, inefficient.

         In contrast, this new gas detector eliminates need for any scheduled maintenance.  Instead, it continually checks its cell, flashing an alarm the instant it fails.

         Replacement is simply pulling the cell, then plugging in a new factory-calibrated cell assembly.

         Engineered to meet anticipated OSHA/EPA regulations, this detector can monitor more than 70 toxic gases, including chlorine, ammonia, carbon monoxide, nitric oxide, plus exotics like arsine, phosphine, titanium tetrachloride, tetrahydrofuran.

         Detectors can team with transmitters to show toxic gas levels on digital readout panels; color-coded LED’s glow green/amber/red if gas concentrations increase.

  • Gas detectors to protect clean rooms, laboratories and similar areas where toxic/explosive gases are a constant hazard have been developed by Minneapolis-based Sensor Electronics.

         Such nasty gases include hydrogen chloride, tungsten hexafluoride, ammonia hydrides, fluorines (as difluoromethane), xylenes and similar life-threatening gases.

         “Tunnel vision” means the detector “sees” only one specific gas – as, say, WF6 – and cannot be confused by other gases that could cause false readings, false signals, false alarms, needless shutdowns and evacuations.

         Stainless-steel construction means these new detectors shrug off corrosion, contamination, condensation, dust, dirt, aerosols, temperature/humidity extremes.

         Factory-tuned for specific gases, detectors can turn on alarms to warn personnel.  If gas concentrations increase the detectors can turn on fans to flood the area with outside air.

  •           A new detector that measures ultra-high ammonia concentrations – from 10,000 to 1 million ppm (saturated) – has been developed by Minneapolis based Sensor Electronics.

          Ammonia (NH3) is both toxic and explosive, meaning leaks from pressurized vessels can be especially hazardous.

         Conventional electrochemical ammonia detectors give reliable readings to, say, 1000 ppm.  Problem is that they don’t respond at higher ammonia levels,  Moreover, they have a short working life – to typically only a year or two – meaning periodic testing, regular replacement.

         In contrast, this new detector works in the long infrared spectrum, meaning extreme accuracy, excellent repeatability, and an operating life measured in decades.

         The detector is engineered for use in power plants, research laboratories, process controls, medical equipment manufacture, fertilizer compounding, commercial refrigeration systems, and the life.

       This fail-safe detector shrugs off corrosive atmospheres; rugged components are immune to sudden shock, continual vibration, electromagnetic interference, temperature/humidity extremes (-40/140 degrees Fahrenheit, 095 per cent RH).

         Detectors can tie into existing control/security networks, or as a stand-alone, work in with dedicated transmitters that show real-time ammonia concentrations on digital readouts:  color coded alarm lights can warn of leaks, dangerous levels, possible product contamination.

  • SEC 3000 Toxic Gas Detector
    Toxic gas detector can detector over a 100 different toxic gases. Hot swap technology you don't have to power down to replace the sensor. Sensor continually checks itself to give constant fail safe protection. ...

  • SEC 3000 gas detector detects over a 100 different gases. Operates as a standard 4-20 mA gas detector or you can couple the detector with the SEC 3100 transmitter or the SEC 3120 dual transmitter.  Hot-swap technology makes changing out a sensor simple.  You just unplug the old sensor and plug in the new sensor.  All that without powering down the system.   New technology this sensor self checks itself which alerts the end user that their sensor is in need of replacing. Stop by our booth for a demonstration!
