The PM2.5/10 Particle Counter is designed for environmental monitoring in industrial, commercial and institutional buildings. The unit provides accurate readings of particle counts in two important sizes, 2.5μm and 10μm. The sensor uses the laser light scattering method which is not subject to drift or sensor contamination. A fixed volume of air is pumped through the sensor and suspended particulate matter in a given unit volume of air is totalized into two bins, one for particles of 2.5μm and another for larger 10 micron sizes. The results are reported in μg/ m3 of air with all data available over the RS485 port for integration into large systems using either the BACnet MS/TP or the Modbus RTU protocols,with an ethernet port.An upcoming model will have two analog outputs, one for each of the two particle size bins.
Humidity & Temp transmitters are designed for environmental monitoring and controlling in industrial, commercial and other buildings. These transmitters can be used for indoor air temperature and humidity monitoring in various industrial plant, clean room, lab, machine room, commercial buildings, airport, and schools. The modbus interface is documented and integrator friendly. They also have transducer outputs for connecting as analog inputs to all popular control systems. Various models are available:Duct Mount,Wall Mount,Room Mount and 2 meter cable.BACnet MS/TP and Modbus RTU protocols over RS485,with an ethernet port.
The CO2 sensor with Humidity & Temp transmitters are designed for environmental monitoring and controlling in industrial, commercial and other buildings. These transmitters can be used for indoor C02, temperature and humidity monitoring. The modbus interface provides easy setup and integration into large systems.Supports Modbus RTU over both the Ethernet port and the RS485 port,supports Bacnet over both the Ethernet port (IP) and the RS485 port (MSTP).
The duct air flow switch provides feedback of air flow in HVAC duct work. It can be connected directly to the control system as a feedback point or can be directly interlocked to prevent operation of heating and cooling equipment when there is no air flow. Stainless steel paddle resists corrosion. Adjustable spring tension screw allows setting the air flow trip point. The paddle can be trimmed down for higher flow applications. The cable enters through the water tight gland, or the gland can be removed and replaced with an EMT or flex connector for wiring with EMT or metal flex.
This Air Quality Sensor is a full-featured CPU based device which is ideal for the detection of Air Contaminants. In residential and commercial environment, the Figaro Sensor has high sensitivity to VOCs and odorous gases. This unit comes with an LCD display with back lighting for easy viewing. It comes standard with humidity and temperature reading capabilities, which are vital when managing air quality control, and with the manual jumper output selection, your readings have never been more precise.
This passive infrared detector, with high stability, has adopted advanced technology in signal processing and provides extremely high detection ability and anti-error alarm. The detector will detect movement of human automatically when intruder passes through the detection area, and it will send out alarm signal to alarm host if there is movement.This product is suitable for the safety of residential houses, villas, factories, markets, warehouses, and office buildings.
Pressure Transmitter is a kind of standard and most popular transmitter applied in air and liquid pressure measuring,since a high sensitivity silicon pressure chip is employed in the sensor.The pressure transmitter is designed for industry application with perfect long term stability,which is the most important specification for industry application.
The CS series Current Sensors are solid state transducers for measuring the current in fans, pumps and other HVAC equipments.Select one of three ranges by moving the jumper on the device to switch between 10A,20A and 50A.This sensor outputs 0-5V directly and requires no power supply. The signal is proportional to the average current and vary slightly from the results shown on an RMS measuring ammeter, depending on the load.
The new clamping / split core current transformer allows installation without interrupting the high voltage wiring. Add a second wrap of the high voltage cable to double the output signal for a given current.
The Single Phase Power Meter with external CT are solid state transducers for measuring the current and voltage in fans, pumps, and other HVAC equipment.The connections are by Modbus.They have two analog output,0-10V&4-20mA.
The series of split core current sensors are designed for fast and easy installation. Split-core transformers are ideal for installation on existing electrical wiring by snapping around the conductor. This method permits a safe, easy and portable current measurement
The float switch is a device used to sense the level of water within a tank,and it can actuate a pump,an indicator, an alarm, or other device. Use it with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, fish tanks, filtration, heating, or whatever your project may be.
The duct sensor is used to measure the supply and return air temperature in HVAC system. There are several sensor elements to choose from which guarantee compatibility with all popular DDC systems. There is a precision thermistor. The probes are epoxy sealed to prevent moisture from migrating into the probe. Field calibration is not generally required. The standard probe length is 12 inch. Custom probe lengths, wire types and sensor elements are available for large OEM projects. Ask about our plastics & metal manufacturing capabilities for custom housings as well.
The temperature sensor is designed to measure outdoor air temperature in typical HVAC applications. Mounting is quick and easy using two screws and no electrical box. The thermistor is a well sealed stainless steel probe which is then inserted into a hard rubber PVC radiation shield. The cable is two meters long which allows terminating inside the building in an electrical enclosure or with flying leads. The cable can exit directly behind the probe and into the building through a hole, or it can exit vertically and run down the wall. A foam backing seals the hole in the wall if there is one and also serves to thermally insulate the probe from the wall. The probe is filled with thermal grease for quick response.
