Water and Liquid Level Transmitter
$32.00 - $45.00Availability: In stockOut of stock
This water and liquid level transmitter measures fluid level in tanks and wells and sends out a 0-10V signal proportional to the liquid depth. Stainless steel construction makes this sensor compatible with most any fluid.
The sensor is temperature compensated and operates accurately over all ambient temperatures.
The sensor head has a baffle to prevent debris buildup making it suitable where there is sludge and other solids mixed with the liquid. The polyurethane cable ensures long-term durability, while the stainless steel body protects against rust. Several models are available for tank depths from one to ten meters.

Current Sensor with 0-5VDC output signal
$13.80Availability: In stockOut of stock
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
$7.80 - $57.00Availability: In stockOut of stock
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
$25.00 - $35.00Availability: In stockOut of stock
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
$6.70 - $12.50Availability: In stockOut of stock
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
$5.00 - $6.00Availability: In stockOut of stock
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
$5.00 - $13.50Availability: In stockOut of stock
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.
