modeldescription
the series gstc carbon monoxide/nitrogen dioxide gas transmitter monitors the gas concentration in underground parking garages and loading docks. The carbon monoxide transmitter is used to measure the exhaust of gasoline engines, while the nitrogen dioxide transmitter is used for diesel engines. The series gstc is compatible with either bacnet or modbus communication protocol, allowing the transmitter to be used with almost any building management controller. The gstc output is communicated over an rs-485 wire via bacnet or modbus communication protocol. To maximize the accuracy of the series gstc, the sensor can be field-calibrated using the a-449 remote lcd display. When the sensor reaches the end of its life, the display will indicate that the sensor needs to be replaced. Bacnet and modbus communication protocol recommend limiting the number of nodes in any segment to 32. Therefore, the transceiver may be rated at one unit load. Fractional loads are also acceptable. The series gstc accounts as an eighth of a load on the ms/tp network.

carbon dioxide and temperature transmitter
the series cdt carbon dioxide and temperature transmitters accurately monitor the co2 concentration and temperature in indoor environments to help achieve energy savings. For increased sensor accuracy, a single beam dual wavelength nondispersive infrared (ndir) sensor is used to automatically correct the measurement in both occupied* and unoccupied buildings against light source aging effects. The single beam dual wavelength sensor technology provides the highest level of accuracy compared to automatic baseline correction methods which can unintentionally shift the calibration based on co2 levels and barometric pressure conditions. In order to achieve a higher level of accuracy, the series cdt includes digital barometric pressure adjustment and the ability to field-calibrate the sensor. For applications that require visual indication, the wall mount configurations of the series cdt can be ordered with an integral lcd display. Push buttons are standard on all configurations of the transmitters for access to the menu structure, but wall mount configurations can be ordered without the buttons. To prevent tampering, the action of the buttons can be locked out using an internal dip switch selection.
for buildings occupied 24 hours per day, it is recommended that calibration be verified every 6 to 12 months depending on application.
single beam dual-wavelength sensor advantages:
automatically corrects for aging effects in occupied and unoccupied buildings. Perfect for hospitals and manufacturing plants that are occupied 24 hours per day
measures actual unfiltered light intensity directly. Eliminates error from incorrect assumptions of gas concentration in theoretical logic assumption methods

Explosion Proof Pressure Transmitter
Series 3200G Explosion-proof Pressure Transmitter
HART Communication, Push Button Configuration, Rangeability (100:1)
The Mercoid Series 3200G Smart Pressure Transmitter is a microprocessor-based high performance transmitter, which has flexible pressure calibration, push button configuration, and programmable using HART Communication. The Series 3200G is capable of being configured with the zero and span buttons, a field calibrator is not required for configuration. The transmitter software compensates for thermal effects, improving performance. EEPROM stores configuration settings and stores sensor correction coefficients in the event of shutdowns or power loss. The Series 3200G is FM approved for use in hazardous (Classified) locations. The 100:1 rangeability allows the smart transmitter to be configured to fit any application.

explosion proof rtd temperature transmitter
series tte explosion-proof rtd temperature transmitter
user selectable ranges, optional lcd display
the series tte explosion-proof rtd temperature transmitter is the ideal product for hazardous temperature measurement applications. The tte series has seven preprogrammed temperature ranges that are selectable via an internal dip switch. For those applications that need a custom range, the transmitter can be easily configured for any range between -30 to 250f with a minimum span of 40f. The span and zero can be quickly adjusted with a simple push button design. This unit has optional listings of fm for use in class i, division 1, groups b, c and d, class ii, division 1, groups e, f and g and class iii atmospheres or atex (directive 2014/34/eu) for ii 2 g ex db iic t6.t4 gb (-20c = ta = + 70c), ii 1 d ex ta iiic t111c da (-20c = ta = + 70c) and iecex for ex db iic t6.t4 gb (-20c = ta = + 70c), ex ta iiic t111c da (-20c = ta = + 70c). The compact housing allows for the transmitter to be mounted in virtually any application.
