1 DREXELBROOK A Leader In Level Measurement Solutions VeriGAP Series Two-Wire Ultrasonic Switch Ideal for Spill Prevention The two-wire gap switch is ideal as a high-level spill prevention system for non-coating liquids. A special patented circuit lets you meet spill prevention regulations and prevent unnecessary down-time, lost products, and regulatory fines. No Calibration Ever The unit needs no calibration or gain adjustments, regardless of the material to be measured. Measurement not affected by variations in liquid viscosity, density, pressure or electrical properties. Simple, Economical Installation One piece design for simplified installation and operation. Two-wire design eliminates the need for line power, conduit, or pull boxes in the field. Sensing element is easily installed in existing vessel openings, and of course...no calibration is needed. Intrinsically Safe Operation Transmitter and signal are FM approved intrinsically safe when powered from an intrinsically safe source. No Calibration Needed The Series two-wire level switch is an integral unit assembly which senses liquid presence by ultrasonic techniques. No calibration of any kind is needed. Completely Self-Checking The optional test checks not only the electronics, but also the relay and the entire control loop, including final control elements. When the circuit is activated at the push of a button, a signal is sent to the electronics to check the integrity of the sensing element and crystals and then simulate a high level in the tank. If the unit alarms, the operator knows that it will respond during an actual high level situation. This feature can also be paired with our Auto receivers, which initiate the test every 10 seconds, but do not let the relays activate any final controls or alarming. If the unit should fail the test, a separate fault relay is activated. A manual override allows for the vital testing of the full control loop. Two-Wire Operation This two-wire device changes its current state from normal to alarm when liquid bridges the sensor gap. During normal operating conditions, the unit draws 14-20mA, and during alarm conditions, the unit draws 4-10mA. Any other currents outside these windows causes Drexelbrook two-wire receivers to generate a fault alarm, giving you continuous loop diagnostics (open and short circuit, disconnected loop wires) and control or indication of liquid level at that

Adjustable from 2 to 36 inches Note 1: Unit will operate above 160 F with reduced component life. Note 2: For critical applications, it is recommended to use a combination of the two wire ultrasonic gap switch and the two-wire RF Admittance transmitter (LCT ) as High and High-High alarms. Both systems have features and can be tied to a single power-supply receiver. Note 3: Other sensors are available. See your Drexelbrook representative for your specific requirement. U.S.A.
