The Q5 Series smart toxic/combustible gas sensor/transmitters use various sensing technologies to detect a wide assortment of gases. The units are housed in a NEMA 4X enclosure with an integral buzzer that will meet the most stringent of applications. All Models feature a LCD display of gas concentration, LED indication of each of the SPDT relays and TX/RX for the RS-485 or Modbus communications. Pre-calibrated sensors can be purchased and installed by the user thereby reducing calibration costs and minimizing downtime. Should a client wish to switch from one gas to another all that is need is to purchase a sensor/board and install it. The user can select multiple screens from the menu that display relay status, time, TWA, STEL, concentration, and other data. Programming and calibration is non-proprietary and is accessed through a user selectable password that protects system integrity. The units can be installed as stand-alone, digitally networked with QEL or other controllers through a RS-485 or Modbus comunication port that is standard. Equally a 4-20 mA, 2-10 VDC and a 1-5 VDC analog output that is fully assignable over a chosen range is standard. User programmable relays and a buzzer are also standard allowing several options to energize relays through instantaneous activation upon a preselected concentration or activation through a time-waited average concentration.
