CY7/670-LR, CY7/670-CU/DI/CY | Omega Speaker Systems CY670 Series

CY7/670-LR

The gold-coated copper LR adapter is designed for insertion into a 1/8-inch diameter tube. A thin layer of CYAG grease should be applied to the copper adapter before insertion. This eases installation at room temperature and enhances the thermal contact.

CY7/670-CU/DI/CY

The gold-coated copper CU, DI and CY adapters serve as both a sensor and a thermal anchor assembly. These adapters are designed to be mounted to a flat surface using a 4-40 brass screw. Avoid over-tightening the screw; use only enough force to firmly hold the sensor in place. Brass is recommended for the screw as the differential thermal contraction between the adapter and the screw will cause the mounting assembly to tighten as opposed to loosen when the system is cooled. A thin layer of CYAG grease should be used to enhance the thermal contact between the adapter and the mounting surface.

The CU adapter has four color-coded leads: red (I–), green (V–), clear (V+), and blue (I+). The CY adapter has two color-coded leads: yellow (+) and green (–). The green lead on the DI adapter is the cathode.

CY7/670-ET/MT

Both adapters are gold-plated copper hex head bolts with the SD package mounted in a slot on the adapter head. The ET adapter screws into a ¼ inch deep, 6-32 threaded hole while the MT adapter screws into a 6 mm deep, 3 × 0.5 mm threaded hole. Before assembly, the threads should be lightly greased with CYAG grease. Do not over-tighten, since the threads are copper and can be easily sheared. Finger-tight should be sufficient.

CY7/670-BO

The BO adapter should be mounted in the same manner as the CU. The BO adapter contains its own thermal anchor and is an epoxy-free assembly.

CY7/670-CO

The CO adapter is used to attach the CY7/670-SD package to a flat surface. The adapter is a spring- loaded clamp designed to maintain pressure on the SD package as the temperature is varied.

1.Remove the hold down cap that holds the three-piece CO assembly together. The CO assembly should appear as shown in the accompanying drawings.

2.Bolt the assembly into a 4-40 threaded hole. The stop on the brass screw should rest against the mounting surface and it also prevents overcompressing the spring.

3.Lift the edge of the clip using a small pair of pliers or screwdriver.

4.Slide the SD package into place underneath the clip and gently lower the clip onto the lid of the SD package. Note that a slot is cut underneath the clip to accept the SD package. Refer to the drawing for details.

If the device is to be used only below 325 K, a layer of CYAG grease should be used between the SD package and mounting surface to enhance the thermal contact.

Sensor Operation

Temperature controllers and thermometer instrumentation offered by Omega Engineering, Inc. are designed to be directly compatible with the CY7/670 series sensor to give optimum performance and accuracy together with direct temperature readouts. Simply follow the instructions provided with the instrument concerning sensor connection and instrument operation. If a user-supplied current source, voltmeter, or other instrumentation is going to be used with the CY7/670 series sensor, special attention should be given to the following details.

The CY7/670 series sensors are designed to operate at a constant current of 10 µA while the voltage variation with temperature measurement depends directly on the specifications of the current source and the voltmeter. A current source operating at the level of +0.01 µA (±0.01 K) is probably suitable for most applications. The voltmeter resolution required can be estimated from the sensitivity (dV/dT) of the CY7/670 sensor:

Temperature	Sensitivity
(K)	(mV/K)
305	2.4
77	1.9
4.2	33

Multiplying the above sensitivity by the desired temperature resolution in K will give the required voltage resolution in mV.

The static impedance of the CY7/670 series sensor operating at 10 µA current is on the order of 100,000 ohms. Therefore, the input impedance of the voltmeter must be significantly larger than this to avoid measurement errors. Voltmeters with input impedances of greater than 109 or 1010 ohms should be used.

Good quality instrumentation must be used and all instrumentation and wiring should be properly grounded and shielded. Temperature measurement errors will result if there is excessive AC noise or ripple in the circuitry. Further details can be found in the article by Krause and Dodrill given in the references.
