Intrinsically Safe Drum High Level Alarm 316 Stainless Steel, Dual alert, Battery powered

Gizmo Engineering IS-DHK-SS is a high-performance intrinsically safe drum level alarm designed to monitor and notify operators of liquid level changes in drums and similar containers used in industrial environments. Built for rugged service and hazardous locations, this unit is engineered to meet strict safety standards while providing reliable, long-term operation in demanding conditions. At its core, the IS-DHK-SS is a high-level liquid alarm - meaning it detects when the liquid inside a drum rises above a predetermined point and signals this condition with both audible and visual alerts. This early warning helps prevent overfills, spills, and costly downtime, making it particularly useful for chemical processing, plating operations, fuel storage, wastewater treatment, and other industrial settings where accurate level detection is critical. One of the key selling points of this product is its intrinsically safe certification. It is rated for Class I, Division 1 hazardous locations, meaning it’s suitable for use in environments where flammable gases or vapors may be present. Its internal circuitry and construction are specifically designed to prevent ignition sources, making it safe for installation in eXplosive atmospheres without requiring eXternal barriers or compleX wiring. The IS-DHK-SS features a robust construction that blends strength with corrosion resistance. The main body is housed in a durable aluminum enclosure, while wetted components such as the pipe and float are made from 316 stainless steel, offering resistance to corrosion from harsh chemicals and solvents. The design also meets IP65 ingress protection against dust and water jets, ensuring dependable operation in wet or dirty industrial settings. Powering the alarm is a replaceable lithium battery system that provides long service life without the need for eXternal power or wiring - a major advantage in remote or hard-to-reach locations. The alarm emits a loud 102 dB buzzer at 2 feet, similar in sound level to a smoke detector, ensuring audible alerts over background noise. Coupled with a flashing LED beacon, it provides a clear, unmistakable signal when a high-level condition is detected. Installation is straightforward: the unit is designed to fit directly into a 3/4 in NPT drum bung, making it easy to mount without special adapters or tools. Adjustable mounting hardware allows the alarm’s float to be positioned at the appropriate depth for the specific tank or drum being monitored.
