The Saga-P logger

In this section:


These guidelines are an addition to the Saga™ User Manual and other materials. They are meant to supplement, not substitute, instructions mentioned elsewhere.

When using Saga-P loggers, you must ensure the proper handling of both the device and the attached probe.

About the Saga-P logger

The Saga™ and the Saga-P loggers are using the same firmware to operate. The only difference is that in operation, the Saga-P logger is configured to read the temperature from the attached probe.


The Saga™ logger has IP55 rating, while the Saga-P logger has IP54 due to the external connector.

Controlant currently provides four different types of probes that cater to various monitoring requirements. Probe specifications

Handling of the Saga-P logger


  • Handle the probe and the logger as one unit by holding both the probe and the logger.

  • Be gentle and avoid sudden movements or use of force.

  • Keep the probe away from sharp edges and serrated surfaces.

  • Keep the probe away from equipment used for cutting or piercing (e.g., utility knives).

  • Make sure the probe's end does not touch the floor or other unsanitary surfaces.

  • Make sure that the end of the probe does not get stuck anywhere when you are moving the device.

  • Keep it away from narrow gaps between surfaces (e.g., between the table and the wall or the floor).


  • Hold the device by holding only the probe.

  • Disconnect the probe from the logger.

  • Pull the probe away from the logger.

  • Try to move a probe by pulling on the logger or using force.

  • Remove the heat shrink tubing at the probe/logger connection.

  • Stretch or apply any tension to the probe.

  • Bend the probe sharply.

  • Coil the probe tightly around the logger.

  • Coil more than five probes together.

Coiling the PR-T80 probe

Occasionally, you might need to coil the PR-T80 probe of the Saga-P logger to return the device to Controlant, for short-term storage, or to prevent the probe from touching the floor while charging.

Always keep the general handling guidelines in mind when coiling the probe.

  1. Place the device on a flat, clean surface that is free from sharp objects.

  2. Gently straighten out the probe to remove any kinks or bends that may have formed during transport or storage.

  3. Hold the probe close to the connector, ensuring not to coil the connector itself (i.e., only coil the white part on PR-T80).

  4. Use your other hand to begin coiling the probe. Coil the probe loosely around the palm of your hand, keeping the coils uniform in size and shape. Avoid twisting or kinking the probe.

  5. Once you have only ~ 15 cm / ~ 6 in left, hold the bundle and the end in one hand to prevent it from unraveling.

  6. Take the remaining probe length in your other hand and wrap it around the outside of the bundle. Continue gently wrapping around until you reach the end while avoiding sharply bending the probe.

  7. Tuck the end between two bigger loops to keep it in place.
