[QUOTE="Sidewinder, post: 512264, member: 9512"] I would not be sure that you are looking at sensors but more actuators in the 4 units. That is the “speakers” that create the ultrasound which does the agitation. You say that you have glued them on. What “exact” procedure for removal of the old and fitting of the new did you undertake? What adhesive did you use? What is the modulus of elasticity for the adhesive in the thickness of application? What is the frequency of the “sensor”? What is the frequency response from the adhesive as applied at the operating frequency? You are looking at micrometer movement of the tank at frequencies above 10kHz probably more. Very little energy in a “sound” wave at such frequency. You might well loose that energy in the wrong way with simply incompatible or too much adhesive. [/QUOTE]
