Use Greystone Energy’s SPC Series for Complete Temperature and Humidity Monitoring.

Greystone Energy’s SPC series is a temperature and humidity transmitter that utilizes a pair of sensors in one sleek wall mount enclosure.  For an environmental monitoring and control system the transmitter’s RH sensor monitors RH over a span of 0-100% and enlists a thermistor that is curve-matched to measure temperature.

Separate setpoint controls are options for temperature and relative humidity adjustment. Also optional are external communications jack and override switch which includes OCC input. Both temp and RH setpoint constant signals are available on individual outputs (0-5, 0-10 Vdc jumper selectable, or linear 4-20 mA.  The SPC Series boasts a low profile, LCD indication and is offered in voltage and current models.  Accuracy selections are 2, 3 and 5%. Alternate configurations of Greystone’s SPC series are available with 1-4 outputs.

Honeywell Analytics 301C Controller

Providing Solutions for Safe Parking Garages

The Honeywell Analytics 301C Controller detects, monitors and controls gases.  It is energy efficiency and easy to install.  The controller can allow up to 126 zoning groups and can manage up to 180 events with programmable latching alarms.  Using an addressable RS-485 communication protocol, the 301C uses daisy chain wiring to connect up to 96 transmitters in three loops. This simplifies installation.  BACnet/IP is available. The 301C’s zoning, voting, and averaging abilities reduce operational and maintenance costs. When the 301C is used for a gas detection, your structure is compliant with the industry’s most demanding safety and energy guidelines. The 301C controller offers automatic sensor identification and unique zoning capabilities. Readings from transmitters can be evaluated by averaging or voting. For example, voting can be used to activate fans only when one-third of the sensors in a zone report gas, thus avoiding excessive response to a single car idling. Time delays can be configured to prevent false alarms or to reduce power cycling of a fan.  The controller can detect when a single sensor reading is higher than others. Responses can be made to match time of day, day of week, or other external input. This flexibility can precisely meet the needs of each installation, thus saving energy and extending equipment life.  The 301C controller provides a complete gas detection network for the intelligent building.
