PM2.5/10 Particle Counter
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. An upcoming model will have two analog outputs, one for each of the two particle size bins.
The fan can be disabled between readings to extend the life of the sensor by adjusting a Modbus register/ bacnet variable. The fan runs for one minute, takes a reading and then goes off for the user defined period which is adjustable from one minute to as long as 250 minutes between readings.

Air Flow Switch
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.

Current Sensor: Single phase
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.

Duct Temperature Sensor
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.

Outdoor Air Temperature Sensor, Overmolded
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.
