Power Adapter – PA-12V
The product is AC to DC switching power transfer device,of which the black pluggable connector fits onto most Temco products, or can be taken off to connect to your own devices.
Occupancy Sensor
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
Single Ended 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.</p>
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.
Terminal Shorting Bar
The Terminal Shorting Bar (10-pin) lets you run a common conductor across multiple Temco T3 controller terminals. It has a high-temperature ABS cover and can be cut for shorter runs or combined for longer ones.
Digital Storage Oscilloscope
This Digital Storage Oscilloscope offers a 128Kpts sampling depth with up to 250× horizontal magnification after pausing. Its ultra-portable design—just 1/62 the size of a desktop unit—features smooth handling, intuitive controls with 4 buttons and 2 wheels, and durable PC-AB alloy construction with a high-elasticity plush sensor.
Relay Board and Transformer
The relay board is designed mainly for isolation between thermostat and a fan coil or air handler, 3 relays @ 12A/125VAC, 6A/250VAC, 2 @110V 1A.
Single Phase Power Meter with CT
The Single Phase Power Meter with internal CT are solid state transducers for measuring the current and voltage of fans, pumps, and other HVAC equipment.The current sensors are available in two types for either AC @ 200A or DC @ 100A applications.The connections are by Modbus.
Split Core Current Transformer, 330mV output
The 330mV AC Split Core Current Transformer easily snaps onto existing wiring with no rewiring. UL listed, it outputs 0–330mV AC, compatible with T3-6CT and Watt Node meters.</p>
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.
Tstat 7 Thermostat
This full-featured CPU based thermostat is designed for small cooling and heating air handling systems in residential and commercial facilities.
Solid State Relay
The LRSSR provides reliable, maintenance-free operation for HVAC and light industrial systems. With a 3V–32V DC input and 28–285VAC output, it ensures precise switching. Features include a status LED, 2500V dielectric strength, UL certification (E256962), 10–40A ratings (higher available), and a durable, safe design.
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.
