Frequently Asked Questions

Have a question? We have the answer! Check out these FAQs and give us a call today for more information.

Q: Do sensors need external power?

A: It depends on the sensor. Several models operate without external power, but some types of sensors (like 4-20mV output sensors) always require a power source. For more information on current sensors or other kinds of sensors, give us a call today.

Q: Can I monitor voltage with a current sensor?

A: No, current sensors are only for amperage. Amperage can be monitored without a direct connection, but voltage monitoring always requires a direct connection.

Q: Why would someone use a solid-core sensor over a split-core sensor?

A: Solid-core sensors are usually more difficult to install because the source needs to be disconnected and run through the center of the unit. However, often they have a higher accuracy level than split-core sensors. For more information on current sensors or other kinds of sensors, give us a call today.

Q: Where are your current sensors built?

A: We carry current sensors from various manufacturers. They are located around the world, but we primarily sell sensors built in the USA, Canada, Korea, and Europe.

Q: What should I consider when choosing a sensor?

A: There are many things you should consider including accuracy, input rating, output signal, size, and the environment it will be in. For more information on current sensors or other kinds of sensors, give us a call today.

Q: Why should I use a hall effect sensor rather than a regular current sensor?

A: The primary reason we see for using hall effect current sensors is that the users need to monitor DC current. Regular current sensors are used for AC current, but DC current can’t be sensed by them.

Q: Do hall effect sensors require external power?

A: Yes. Unlike regular current sensors, Hall Effect sensors ALWAYS require external power.

Q: Do hall effect sensors come in split-core versions?

A: Yes, hall effect sensors come in solid core and split-core designs. This makes them easy to use in new construction and retrofitting older construction. For more information about current sensors, give us a call today.

Q: Can hall effect sensors monitor current in more than one direction?

A: Yes, some hall effect current sensors are designed to monitor DC current in more than one direction. They can determine if a device is charging or discharging.

Q: What are some important things to keep in mind when choosing a hall effect sensor?

A: Like standard current sensors, you should consider all the same factors. In addition to those factors, though, you should consider if you are going to be using this for AC or DC current, if you need to monitor the direction of the current, and what power supply you will have available to power the sensor. Unlike standard current sensors, often hall effect sensors require uncommon voltage power requirements.

Q: What is the lead time on shipping of products?

A: Lead time varies by product and manufacturer, for an estimated timeframe reference the product page of the model you are interested in.

Q: I am interested in ordering parts but live in another country, do you ship internationally?

A: Yes. We regularly ship internationally most countries. If you have more questions regarding your particular location, please inquire at

Q: Where can I get a copy of my invoice or receipt?

A: Please contact our accounting department for any questions on invoices, receipts, or billing issues at

Q: What if I need pricing on parts, can I get a quote?

A: Yes. We can help with any information on a part needed. Please email or call us at 303-772-6100 and we will be happy to provide additional information on parts or products you need. If needed, we can provide “official quotes” for any of the products we sell.

Q: Do you sell cellular routers?

A: Yes. We distribute cellular routers from different manufacturers. In addition, we sell data packages for those routers from the three largest US cellular providers. You can find more information on these from this link: Cellular & Network Communication.
