Features
For quick analog transmitter replacement, the instrument may be configured with default sensor data, zero level offset, differential process SG, and zero/span procedure only.
Accurate, high-gain analog-to-digital conversion enables measurement of small changes in the process variable. This allows for use in difficult liquid level, interface, or density applications.
An internal temperature sensor enables consistent performance of the digital level controller, despite ambient temperature changes.
Mechanical safeguards designed into the digital level controller help to withstand physical abuse often incurred during installation or in transport, without compromising performance.
Field wiring connections are in a compartment separated from the electronics. This protects the electronics from any moisture brought into the housing by the field wiring.
Includes self-diagnostics that detect an error that may render the process variable measurement inaccurate.

 

 

 

 

 

Using the Field Communicator, you can perform several operations with the DLC3010 digital level controller. You can interrogate, configure, calibrate, or test the digital level controller. Using the HART protocol, information from the field can be integrated into control systems or be received on a single loop basis.

DLC3010 digital level controllers are designed to directly replace standard pneumatic and electro-pneumatic level transmitters. DLC3010 digital
level controllers mount on a wide variety of caged and cagelss 249 level sensors. They mount on other manufacturers’ displacer type level sensors through the use of mounting adaptors.

249 Caged Sensors (see table 1-6)
249, 249B, 249BF, 249C, 249K, and 249L sensors side-mount on the vessel with the displacer
mounted inside a cage outside the vessel. (The 249BF caged sensor is available only in Europe, Middle East, and Africa.)
249 Cageless Sensors (see table 1-7)
249BP, 249CP, and 249P sensors top-mount on the vessel with the displacer hanging down into the vessel.
249VS sensor side-mounts on the vessel with the displacer hanging out into the vessel.
249W wafer-style sensor mounts on top of a vessel or on a customer-supplied cage.

 

 

 

 

 

 

Main technical parameter

communicating, the voltage of controller ≥17.75V DC)

Output signal: 4~20 mA DC (Positive direction – the increase of level, interface, or density make output

increase; Negative direction – the increase of level, interface, or density make output decrease.)

Measuring range: 300mm—2500mm (can also over range)

Ambient temperature: –40ºC to +80ºC (when ≤–30ºC, no LCD display)

Operating temperature: –70ºC to +400ºC

Measuring accuracy: 0.5%

Influence from power supply: When the voltage of the power supply varies between min. and max. ,the output change is within <±0.2%. of the full scale.

LCD display: Output current signal,process variable,process temperature,percentage range,rotation angle of torque tube.
