APG DST-2421 DST Mid-Range Ultrasonic Sensor

Description

The DST series is APG’s line of ultrasonic sensors used in conjunction with a DCR controller to give you a simplified, stand-alone system. The transmit and receive circuit is built into the sensor and digitally communicates the detected distance to the DCR controller. This allows the sensor to be separated from the DCR controller by up to 2000 feet (610 meters) with no signal loss.

How To Read Your Label

Each label comes with a full model number, a part number, and a serial number. The model number for your DST will look something like this:

  • SAMPLE: DST-2421-C10

The model number tells you exactly what you have. You can also call us with the model, part, or serial number and we can help you. You’ll also find all hazardous certification information on the label.

Installation Guidelines

Your DST should be installed in an area–indoors or outdoors–which meets the following conditions:

  • Ambient temperature between -30°C and 60°C (-22°F to +140°F)
  • Ample space for maintenance and inspection

Additional care must be taken to ensure:

  • The sensor has a clear, perpendicular sound path to the surface being monitored.
  • The sensor is mounted away from tank or vessel walls and inlets.
  • The sound path is free from obstructions and as open as possible for the 9° off-axis beam pattern.
  • The sensor is tightened by hand to avoid cross-threading.

Important: For the user interface guide and sensor configuration, see the DCR-1006A user manual.

IMPORTANT: Refer to section 10 for Hazardous Location Wiring.

Connecting to a DCR

DCR-1006A wiring terminals are accessible by unscrewing and then lifting off the front (top) face.APG-DST-2421-DST-Mid-Range-Ultrasonic-Sensor-fig-

NOTE: For programming the DCR-1006A controller, please see the DCR-1006A User Manual.

General Care

Your ultrasonic sensor is very low maintenance and will need little care as long as it was installed correctly. However, in general, you should periodically inspect your DST sensor to ensure the sensor face is free of any buildup that might impede the function of the sensor. If sediment or other foreign matter becomes trapped on the sensor face, detection errors can occur.

If you need to remove the sensor, be sure to store it in a dry place at a temperature between -40° and 180° F.

Repair Information

If your DST ultrasonic sensor needs repair, contact us via email, phone, or online chat on our website. We will issue you an RMA number with instructions.
