Lightning Detection &
Warning Devices
Warning means having information in advance that allows the user to start temporary preventive measures before the storm begins. Lightning detection and warning will be complementary to an installed Lightning Protection System (LPS) in certain situations, while in others it will be sufficient to act alone.
Beautiful to behold, lightning is not only one of nature's most powerful phenomena, but one of the most common and destructive. That's why Dhruva Technologies provides Boltek Lightning Detection and Warning Systems that help you to detect and track thunderstorms up to 300 miles away, right from your personal computer. Dhruva Technologies is the only authorized partner of Boltek products in India right from the beginning.

Short Range Detection Systems
For complete short range detection, we provide all the necessary components to setup a lightning detection system with the appropriate accessories.
The EFM-100 kit comes complete with a high accuracy short range detector, inverted mounting hardware, cables and adapters. It is designed to provide a real time reading of the electrical field in the atmosphere with a time vs e-field graph displayed on a computer along with lightning strike distances accurate to within one mile.
The ERL-10 Programmable Output Relay Module Kit comes complete with lightning detector(s), cables and inverted mounting hardware for the EFM-100. It is ideal for setups looking to connect external devices for either a visual or audible alert system. It can also be setup to connect to a PLC or datalogger. The ERL-10 output data by default is through a USB connection or a RS485 adapter can be connected easily for longer connections.
EFM-100C RS485 Electric Field Mill Kit
High accuracy short range lightning detection from 0 to 24 miles (0 to 38km) with the capability to receive lightning alerts on your cell phone or email while out in the field.
The EFM-100 not only detects nearby lightning but can detect the atmospheric conditions which precede lightning. Electric field data is displayed and graphed on your desktop computer using the included software. For complete electrical isolation from the field mill outside, the EFM-100 connects to your computer using a fiber optic cable. The EFM-100 features aluminum and stainless steel construction for corrosion resistance, gold plated connectors throughout, and the highest quality ball-bearing brushless DC motor for excellent reliability. The electric charge contained in a thundercloud also generates an electric field. This field can be measured on the ground. Electric fields develop wherever there is a difference in electric potential. If the electric field gets high enough you can feel your hair stand on end (if this happens outdoors during a thunderstorm crouch down with your feet together as you are about to be struck by lightning.) An electric field is what attracts your hair to a charged comb or a charged balloon.

ERL10-KIT1 RS485 Lightning Detection Package
High accuracy short range detection with three programmable alert level relay outputs designed for use with the EFM-100. This kit includes the inverted EFM-100 with pole mount, and pre-wired waterproof enclosure with the ERL-10, EFA-21 (or EPM-1), relay output expansion cable and fault buzzer. Status monitor display.
Operation
The ERL-10 receives data from the EFM-100 Electric Field Mill short-range sensor (20 miles/32 km). It constantly monitors for lightning and activates its timed relay outputs when lightning is detected. Up to three alerts can be configured, referred to as Red, Orange and Yellow Alert levels. The green All Clear state is entered when no lightning has been detected within the configured time period. When the ERL-10 is first turned on, it enters Survey Mode where it looks for lightning. After several minutes without lightning (configurable but typically 10-20 minutes) the system enters the All Clear state. The green All Clear light on the ERL-10 illuminates and the All Clear relay output activates.
Status Monitor
The ERL-10 Status Monitor software (included) allows the system status and countdown timers to be displayed. Countdown timers clearly indicate the number of minutes until All Clear. Alert activations are timestamped and logged to disk. Graphical log file viewing software is also included.

ERL10-KIT2 Duel Sensor Lightning Detection Package
Operation
The ERL-10 receives data from the EFM-100 Electric Field Mill short-range sensor (<20 miles/32 km) and a LD-250 long range lightning detector. It constantly monitors for lightning and activates its timed relay outputs when lightning is detected. Up to three alerts can be configured, referred to as Red, Orange, and Yellow Alert levels. The green All Clear state is entered when no lightning has been detected within the configured time period.
When the ERL-10 is first turned on, it enters Survey Mode where it looks for lightning. After several minutes without lightning (configurable but typically 10-20 minutes) the system enters the All Clear state. The green All Clear light on the ERL-10 illuminates and the All Clear relay output activates.
Dual Sensor Coincidence Mode
With Coincidence Mode enabled, a lightning strike must be detected by both the EFM-100 and the LD-250 in order for an alert to activate. This virtually eliminates false alerts that could be caused by persons, animals, insects, etc. near the EFM-100 sensor. Coincidence Mode is only applicable within the range of the EFM-100 (0-20miles/0-32km).
Status Monitor
The ERL-10 Status Monitor software (included) allows the system status and countdown timers to be displayed. Countdown timers clearly indicate the number of minutes until All Clear. Alert activations are timestamped and logged to disk. Graphical log file viewing software is also included.
