Water Leak Detector The very affordable Series WD2 Detects Leaking Conductive Fluids and alarms to prevent the leak from creating costly damage. The WD2 relies on the electrical conductivity of water to change the resistance across the two contacts located at the base of the enclosure. Model WD2-BP2 is battery powered, provides audible alarm, LED visual alarm,and a SSR output.Also featured is a low battery warning. WD2-LP units are line powered and include a green power indication LED. Mounting bracket A-154 is perfect for use in leak pans where it is desired to raise the sensing level above the bottom of the pan to eliminate nuisance alarms. The bracket can be mounted to the bottom of the pan and the height of the WD2 adjusted anywhere up to 1.75 ¿¿ (44.5 mm).Or the bracket can be used to mount the WD2 to the side of the drip pan or any side wall at desired height. Specification: Electrical Rating :WD2-BP2:Pilot duty rating 250 mA @ 24 VDC maximum; WD2-LP: 1 A @ 24 VAC/DC, 1 A @ 120 VAC. Audible Alarm :BP Models:10 seconds on, 30 seconds off. LP Models: Continually on. None on D2 model. LED Alarm :BP Models: 10 seconds off, 30 seconds on. Two red LED’s; LP Models: Continually on. Eight red LED’s. Power Requirements :BP models: 3 V CR2450 lithium metal battery,installed non-functional, user replaceable;LP Models;11 to 27 VAC/DC. Power Consumption :BP Models: 0.9 mA steady state non-alarm, 3.0 mA during audible alarm, 2.4 mA during LED alarm; LP Models: DC power: 25 mA typical and 75 mA maximum, AC power: 30 mA typical and 85 mA maximum. Weight : WD2-BP2: 3.5 oz; WD2-LP: 4.3 oz; WD2-LP-D: 5.6 oz. Operation: Model WD2-BP2 is battery powered, provides audible alarm, red LED visual alarm, and a SSR output. When conductive fluid is detected, the audible alarm will turn on for 10 seconds followed by a 30 second visual alarm repeated until the unit no longer detects fluid. The SSR will change state from open to closed. When the battery gets low the WD2 gives a warning by turning on the visual and audio alarms. WD2-LP units require an 11 to 27 VAC/DC power supply. A green power LED illuminates when the unit has power. WD2-LP units provide audible alarm, red LED visual alarm, and either a SPDT or DPDT output. When conductive fluid is detected, the audible alarm and visual alarm will turn on and stay on. The relay will change state with open contacts going to closed and closed contacts going to open. Mounting: The unit is made to place on a horizontal surface where leaking fluid can build up. Mounting bracket A-154 is perfect for use in leak pans where it is desired to raise the sensing level above the bottom of the pan to eliminate nuisance alarms. The bracket can be mounted to the bottom of the pan and the height of the WD2 adjusted anywhere up to 1.75 ¿¿ (44.5 mm). Or thebracket can be used to mount the WD2 to the side of the drip pan or any side wall at a desired height. The A-154 includes one “U” bracket and two “L” brackets. For bottom mounting unscrew the body screws in the top of the WD2. Install the “L” brackets to the “U” bracket sides using the screws and nuts provided. Keep the screws loose for later adjustment of WD2 height. Place the “U” bracket on the top of the WD2 and line up the holes in the bracket with those in the body. The A-154 includes longer body screws that are used to now screw down both the bracket and the body top. The “U” bracket can be mounted in the up or down orientation but it must be mounted “down” to reach the full 1.75 ¿¿ height potential

The float switch is a device used to detect the level of liquid in the tank, it can start pumps, indicators, alarms or other devices.The sensors are usually mounted in the bottom or in the lid of the liquid container also can control the upper and lower fluid level. The sensor has a float with a built-in magnet, liquid buoyancy moves the float over the tube, which causes the opening or opening of the built-in reed switch.

Ground Penetrating Radar
Get Price Quote
We are offering ground penetrating radar (gpr) is a totally non-destructive technique to produce a cross section profile of subsurface without any drilling, trenching or ground disturbances. The profiles are used for detecting buried utilities, such as, pipes, cables, etc in totally non-destructive manner. Additionally, subject to requirements, we also use cable & pipe locators, and for precise definition of locations, we use dgps and electronic total stations. The system operates by detecting subsurface changes in em properties (dielectric permittivity, conductivity, and magnetic permeability) which in a geological setting are functions of soil and rock material, water content, and bulk density. Data is acquired by transmitting high frequency electromagnetic (em) signals into the ground which are reflected from various boundaries possessing em property contrasts. The equipment receives the reflected waves over a selectable time range and displays them in real time on screen. The reflected wave data is also saved in appropriate memory for later processing and interpretation. Gpr measurements are used in geologic, engineering, hydrologic, and environmental applications. The company provides the following services using gpr: (a) mapping geologic conditions, such as, depth to bedrock, depth to water table, depth and thickness of soil strata on land and under fresh water bodies, location of subsurface cavities and fractures in bedrock. Mapping landfills and trench boundaries, and contaminants (b) location of buried utilities, such as, pipes (metallic and non-metallic), electric cables (induction locator is further used to identify live cables), drums, tanks, sewers, and boulders. (c) conducting investigations for archaeological and forensic applications. (d) conducting studies, such as, roads and railroad track-bed studies, and highway bridge scour studies. (e) inspection of brick, masonry, and concrete structures.
