Voltage sensors are used to determine presence of voltage while a current sensor is used to determine presence of current. A current transducer, on the other end, converts temperature or pressure into a electrical signal.
A voltage sensor is a very useful tool that makes you feel confident in handling basic home electrical projects. With it, you can replace a switch, receptacle, light fixture, doorbell or thermostat. It is a safe method for testing presence of AC or DC electricity before moving forward.
Volatage sensors, voltage transducer, current sensors and current transducers are very easy to use. For a non-contact voltage sensor, the tip is placed near a device or wire where the AC is suspected to be present. The tip responds by illuminating or changing color from its standby mode. Some have sound and so they might produce sound when they sense presence of voltage.
For those asking how to select a voltage sensor, current sensor or current transducer, it is good to check evaluations and specifications. Rarely do we do that. Some will be compulsory features while some are not. For instance, you might want to buy one that has a low sound level for usability at home. For those with audio capability, there are db levels listed.
A low-voltage or dual range detector to check thermostats and doorbells is what is needed. These are rated at 24 VAC and lower.
Because single household circuits range from 110-240 VAC, you do not need a 600 or 1000 VAC capable detector. In fact, that range is only needed for use by professionals who are trained to work on higher voltage applications. An example is to test voltage for power coming to the circuit panel.
The dual-range types (ranging from 12-1000VAC) can be used to detect voltage on AC electric throughout home: outlets, cords, switches, circuit breaker, power strip, thermostats and doorbells. They can detect this before and after transformer. They can also be used to detect voltage presence on humidistat, and security systems.
Current sensors can also be alternating current or direct current sensors. It could either be having an analogue output that duplicates wave shape of the sensed current or a bipolar output that duplicates wave shape of sensed current. A unipolar output is proportional to average or RMS value of the sensed current.
The other type is a direct current input type. This is either a unipolar output, which duplicates wave shape of sensed current. There is also the digital output option that switches when sensed current exceeds a given threshold. The type to choose depends on your application and as usual, you can consult on the same or do some investigation/research on the matter before purchasing. For many people there is no time for that, because a home voltage sensor is low cost and is something you will not be using a lot of times anyway. Nevertheless, it can help a lot for those who love DIY electrical projects at home.
