How to Abrade the Transducer
- Only abrade the transducer once housed in the sensor body.
- Abrade the top surface of the transducer – the higher part with 14 black dots – using the abrasion block supplied.
- Be cautious to ensure the abrasion block remains horizontal to the surface.
How to Replace the Transducer
- Only remove the transducer if informed to do so by the program on Tera Term.
- The software will inform you to do this at one of two times: after data collection, or in the pre-deployment scan check.
Always ensure the sensor is dry before removing the transducer
- Using the spanner unscrew the three large bolts in the titanium plate until they begin to spin freely.
- Pull on the titanium plate to remove the array from the body as illustrated below.
- Using the supplied towel, dry the cavity formed by the missing transducer.
Important note: the transducer can only be inserted in one orientation – if solid resistance is felt in the early stage ensure rotation is correct.
- Take the replacement transducer complete with plate, bolts, and nuts from the case or from a newly ordered part.
- To ensure you always possess a working transducer we recommend you purchase a new spare transducer at this point as they can have up to 8-week lead times.
- Apply silicone grease to the perimeter of the O-rings ensuring a thin and even covering.
- Using the three large bolts as a guide locate the correct rotation.
- If correct location is found the transducer should freely fall into the cavity until the lower O-ring.
- With minimal force, press the transducer in until the bolts contact the sensor body.
- Using the provided 8mm spanner tighten the bolts until the transducer is flush with the sensor body. Each bolt should be tightened incrementally.
- If the transducer is not flush with the body, you will not get any data and may damage the lifetime of the array.
