Sensors
Current Sensor with 0-5VDC output signal
The CS series Current Sensors are solid state transducers for measuring the current in fans, pumps and other HVAC equipments.
Split Core Current Transformer, 330mV output
The 330mv AC series of split core current sensors are ideal for installation on existing electrical wiring by snapping around the conductor without requiring and rewiring or interruption of the existing power cabling. UL listed product.
The current flowing through the core of this CT produces an output signal from 0 to 330mv ac, proportional to the current. The signal is a low voltage mv ac signal which needs signal conditioning before going into the typical controller.
The 330mvac signal is compatible with our T3-6CT and the Wattnode power meter on this site.
Dual Float Switch
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.
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.
WTS Series Water Temperature Sensor
This sensor is used to measure water temperature of heated or chilled water and other liquids in mechanical systems. The sensor is called an immersion type where the sensor is mounted in a brass or stainless steel thermowell which allows the probe to be removed from the pipe without draining the system and protects the probe.There are four thermistor based models, and one RTD version to provide compatibility with the majority of DDC systems.
High temperature probe for Floor Heating & Solar applications
This temperature probe is suitable for a variety or high temperature applications such as floor heating, solar heating systems and domestic hot water heaters to name a few. The sensor element is housed in a stainless steel probe which is 6mm diameter x 50mm [2in] long. The cable is 4.5 meter long and is a high temperature material that is tough and highly durable.The probe is available with custom thermistors and Pt elements, nearly all the popular ranges are available with very small minimum order quantity.
Platinum Temperature Sensor
This Probe Temperature Sensor is a 1K Platinum coming standard with an 8″ length Stainless Steel Temperature Sensor.
WTS6-E: Strap-On External Temperature Sensor
The strap-on temperature sensor is used for sensing the temperature of pipework in heating, ventilation and air conditioning systems.
WTS6-I: Strap-On Insert Temperature Sensor
The strap-on Insert sensor consists of a stainless steel sheath temperature sensor, thermal conducting compound, and an adjustable pipe bracket accessory. The stainless steel sheath temperature sensor is suitable for direct application to pipe surfaces for chilled or hot water measurement.
Pitot Tube
The Pitot Tube is a differential pressure producer suitable for air flow measurement.It includes multiple sensing points to measure total and static pressures. It is easy to install and cost effective. It offers simple, low cost installation into pipes and ducts, and high energy savings due to its low unrecovered pressure loss. There are no moving parts or sharp edges to wear, so long term accuracy can be maintained. It contains a lid,connector and two 1 meter length pipes.All Extrusion pipe could be cut on site with a hacksaw,no need a special tool.For example:Buy a 12″ long pipe,and cut to 8″,buy 1m long pipe and cut to the length needed.
Split core Current Transformer, 5A output
The split core current transformer are used for monitoring power of large electrical loads and electrical services. Current flowing in the primary conductor creates a proportional current in the secondary output coil with a range of 0 to 5 amps. This is typically used to drive current indicators on large electrical panels. It is also compatible with commonly used power meters in the industry such as our Three Phase Power Meter.
are ideal where space is limited, such as when metering multiple loads within a panel board. Use for current measurement, energy metering, load surveys, demand metering, energy research, and submetering applications.
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.
