Humidity Sensor with Waterproof Connector
This is a highly durable and stable stable humidity and temperature sensor mouned in a waterproof connector housing. This can be used in applications such as agricultural and extreme outdoor environments.
General Purpose Relay
Featuring top-mounted terminals, this enclosed power relay has a flange-type mounting bracket for mounting in panels and ductwork. These relays are good as status points for high voltage circuits, connect the coil to the high voltage equipment and wire the dry contacts directly into the low voltage side of any of the controllers and thermostats on this site. The spade terminals make for easy troubleshooting in the field and good isolation of high & low voltage circuits.
High power switching capacity for motors and other inductive loads. The standard stocking item is the 20 amp version though we have 30 and 40 amp available as well as other variations shown in the datasheet, by request.
Differential Air Pressure Switch
PSN40-400A differential pressure switch is used for fan status and dirty filter applications. A knob with pressure values on it allows the setpoint to be adjusted visually in the field. The plastic duct probe tubes, flexible silicon tubing and the mounting screws are included with all models.
RTS3 Flush Mount Hidden Room Temp
The room temperature sensor provide precision room temperature sensing in a discreet button form factor for all popular DDC systems.
Probe Temperature Sensor
This Probe Temperature Sensor comes standard with a 15mm Stainless Steel Temperature Sensor. This sensor is a 10K Thermistor, with an industry standard Type 2 curve.Connected to the end of the Sensor is 2 UL2468 26/2CAWG 105°C Black Wires with tinned ends.
Tamper Proof room temperature sensor
The tamper proof room temperature sensor with Torx security screws designed for use with building automation systems in commercial buildings, hospitals, museums or other facilities requiring accurate measurement of room temperature. This sensor can be directly mounted to drywall or an 11-10 electrical handy box.
Pressure Sensor
The Pressure Monitor is used to measure differential pressure in the range of +/-1″ wc full scale, +/-8″ wc, 0 ~100 PSI,0~250 PSI.It combines precision, high sensitivity silicon sensing capabilities and the latest ASIC technology to substantially reduce offset errors due to changes in temperature, stability to warm up, long term instability and position sensitivity. BACnet MS/TP and Modbus RTU protocols over RS485,with an ethernet port.
室外空气温度传感器
This sensor is used to measure the outside air temperature to allow the DDC system to coordinate the mechanical systems with actual building load conditions, enabling such strategies as free cooling, optimum start/stop, and supply temperature reset. The housing is made from PVC and stainless steel fittings which shield the probe from direct sunlight. There are three thermistor based models, and one RTD version to provide compatibility with the majority of DDC systems.
Connectors
The connectors,also called plug-in terminal blocks, provide the wire size from 0.08mm2 to 16mm2. It is available with different pitches from 2.5mm to 10.16mm.You can choose insert direction, contact direction, plug-in direction according to requests.
Floor Heating Manifold & Electro-thermal Actuator
The manifold is designed for use in floor heating systems to regulate heat. It controls flow and return,with the option of connecting up to twelve floor heating circuits.The electro-thermal actuator is designed to control the flow of a hot water pipe to control indoor temperature.
Duct Temperature Sensor – Flange Mount
This sensor is used to measure the supply and return temperature in HVAC system. The flange mount design makes it easy to install the sensor in tight quarters. There are several sensor elements to choose from which guarantee compatibility with all popular DDC systems. The probe in the photo is our standard model which is always in stock, it has a 8″ probe and a 120″ cable, and employs either a precision thermistor or platinum film sensor, so field calibration is not required. The 10ft(3m) cable is “Plenum Rated”.
Dimmable Ballasts
The dimmable ballasts provide a continuous and individual control of lighting sets,develop a standard for lighting control, which creates more convenience and flexibility for lighting systems while reducing system costs.
