Rosemount 2160 Wireless Vibrating Fork Liquid Level Switch   - Reliable Performance In Demanding Applications

WirelessHART vibrating fork liquid level switch combines Emerson’s wireless expertise with the Rosemount 2100 series vibrating short fork technology.  It has all the same features as the wired level switches in the Rosemount 2100 series, but without the complication and cost of wiring. Features include a complete range of process connections, aluminum housing, a choice of wetted parts materials, dry-to-wet and wet-to-dry switching functions, extended fork lengths, and hazardous area approvals.

The Rosemount 2160 continuously performs instrument health diagnostics of the fork and sensor. These diagnostics can detect external damage to the forks, internal damage to the sensor, excessive corrosion and over-temperature. The 2160 can withstand temperatures from -94 °F (-70 °C) up to 500 °F (260 °C) and pressures to 1450 psig (100 bar g).

The Rosemount 2160 wireless vibrating fork liquid level switch extends the full benefits of PlantWeb® to previously inaccessible or uneconomical locations due to the high cost of wiring in a wide variety of challenging applications.

Applications :

 

Overfill Protection

Spillage caused by overfilling can be hazardous to people and the environment, resulting in lost product and potentially high clean up costs.

 

High and Low Level Alarm

Maximum and minimum level detection in tanks containing different types of liquids are ideal applications. The Rosemount 2160 is robust and operates continuously across the temperature range of -94 to 500 °F (-70 to 260 °C) and operating pressures of up to 1450 psig (100 bar g), making it perfect for use as a high or low level alarm. It is common practice to have an independent high level alarm switch as a backup to an installed level device in case of primary failure.

 

Pump Control (Limit Detection)

Batch processing tanks often contain stirrers and agitators to ensure mixing and product ‘fluidity’. The standard user-selectable time delay, from 0 to 3600 seconds, virtually eliminates the risk of false switching from splashing.

 

Pump Protection or Empty Pipe Detection

With the fork projecting only 2 in. (50 mm) (dependant on connection type), the 2160 can be installed in small diameter pipes. Short forks mean minimum intrusion on the wet-side and allow for simple, low cost installation at any angle into tanks or pipes.

 

Extreme Temperature Applications

The 2160E is designed for extreme temperatures and is suitable for continuous operation within the temperature range of -94 to 500 °F (-70 to 260 °C).

 

Hygienic Applications

With the highly polished forks option providing a surface finish (Ra) better than 0.4 µm, the 2160 meets the most stringent hygienic requirements used in food and beverage, and pharmaceutical applications. Manufactured in stainless steel, the 2160 is robust enough to easily withstand steam cleaning (CIP) routines.
