Rosemount™ 2130 Level Switch - Vibrating Fork

Rosemount 2130 Level Switch is developed for challenging applications, tough operating conditions and safety critical environments. Its robust construction and built-in powerful diagnostics will allow you to focus on the essential part - your plant. It is a plug-and-play device, which means that it is easy to install and does not require any advanced configuration or calibration. It is also virtually unaffected by process conditions, which makes its measurements extremely reliable. The Rosemount 2130 is SIL 2 certified for safety instrumented systems. It will make sure that you stay safe from overfill, while at the same time optimizing your tank usage.

• Equipped with fork health monitoring, the device realizes if maintenance is needed
• Magnetic test point makes proof testing of the Rosemount 2130 easy
• Adjustable switching delay enables easy handling of turbulent or splashing conditions
• Explosion-proof/flameproof, and intrinsically safe options available
• Fast drip fork design gives a quicker response time, especially with viscous liquids

1. Exceptional Reliability and Simplicity

· "Detect and Stop" mechanical principle: vibration stops when the fork is immersed, changing the relay state. This simple and direct operation ensures high reliability and is virtually maintenance-free.

2. High Versatility for Virtually All Liquids

· Sensitive only to density, making it immune to flow, bubbles, turbulence, conductivity, dielectric constant, or viscosity (within a range) changes. Suitable for water, oil, chemicals, slurries, dyes, and more.

3. No Moving Parts, Low Maintenance

· Rugged, monolithic fork design with no moving parts that could be jammed by sticky or buildup-prone media. Offers long service life with minimal maintenance.

4. Easy Installation and Setup

· Standard electrical and process connections enable quick installation. Requires no complex calibration; typically, a simple two-point setup (empty/full) is all that's needed for commissioning.

5. Rugged Construction for Harsh Environments

· Fork is typically made of 316 Stainless Steel or Hastelloy for corrosion and abrasion resistance. The housing is robust and can withstand process shock.

· Detection Principle: Piezoelectrically Driven Vibrating Tuning Fork

· Detection Type: Point Level Detection (Level Switch)

· Output Signal: Relay Output (SPDT or DPDT)

· Supply Voltage: Typical 24 V DC or 100-240 V AC

· Density Sensitivity: Typically ≥ 0.7 g/cm³ (lower density models available)

· Process Temperature: -40°C to 150°C (dependent on seal)

· Process Pressure: Up to 100 bar

· Process Connection: 3/4" NPT, 1" NPT, Flange, Sanitary Clamp, etc.

· Fork Material: 316L Stainless Steel, Hastelloy C-276

· Safety Certifications: ATEX, IECEx, FM, SIL, etc.
