STATIONARYINSTRUMENTSSENSOR TRANSMITTERSLocated in Irvine, California, International SensorTechnology (IST) manufactures both the sensors and theinstrumentation used to detect over 150 different toxicand combustible gases for area air quality and safety applications.Since 1972, IST instruments have served alarge and diverse customer base, with users including refineries,chemical plants, semiconductor facilities,hospitals, food and beverage companies, and many others.In fact, our equipment was even chosen by NASA foruse in the Space Shuttle program.IST offers a complete line of instrumentation, includingportables, single and multi-point stationary instruments,stand-alone sensor transmitters, and computerized gasmonitoring systems. Besides offering a complete line ofinstrumentation, IST also offers the most comprehensivechoice of sensor technologies available today, including:• IST’s patented Solid-State Sensor• Infrared Sensor (IR)*• Catalytic Bead Sensor• Electrochemical Sensor• Photoionization DetectorWith this vast array of sensor and instrumentationchoices, IST has the right solution for your gas monitoringapplication.*Patent PendingSTANDARD TRANSMITTERMODEL SM95The Model SM95 sensor transmitter is housed in an explosion-proofcasing rated for Class 1, Div. 1, GroupsB,C,D (UL & CSA approved). It operates on 14-24 VDCpower and provides a linear 4-20 mA output proportionalto the gas concentration. The SM95 can operate as astand-alone instrument or can be used in conjunctionwith any of IST’s complete line of control units which displaythe readings and provide alarm relays. When usedwith any of IST’s MP Series of control units, automatedcalibration is provided, enabling calibration without theneed to adjust potentiometers. The SM95 can beequipped with Solid State, Electrochemical, CatalyticBead, or Infrared sensors.INTELLIGENT TRANSMITTERMODEL 4-20IQThe Model 4-20IQ is a microprocessor based, intelligentsensor transmitter which features a digital display of thegas concentration. Operating on 14-24 VDC power, it alsoprovides a linear 4-20 mA output and, like the SM95, ishoused in an explosion proof casing rated for Class 1, Div.1, Groups B,C,D (UL & CSA approved). It can operate asa stand-alone instrument or can be used with any ISTcontroller, which display the readings and provide alarmrelays.The 4-20IQ comes equipped with a non-intrusive automatedcalibration feature which allows the unit to becalibrated without adjusting any potentiometers. Simplyapply calibration gas and the 4-20IQ will automaticallymake the necessary calibration adjustments. Operatingthe 4-20IQ is accomplished by using a magnetic wandto activate magnetic switches located on the front panel.Thus, all functions can be performed without removingany covers, meaning there is no need to declassifyareas being monitored. Like the SM95, the 4-20IQcan be equipped with Solid State, Catalytic Bead,Electrochemical, or Infrared sensors.
