Ultra Low Level DC Voltage Amplifiers
-
The EM A10 is a low level amplifier module for sensitive measurements, data collection and systems, where signals below 1 nanovolt may be measured. It is ideal for the input unit for precision voltage measuring systems, requiring voltage sensitivity for measuring low noise and low impedance sources. The noise level of the A10 is equivalent to a perfect resistor of about 20 ohms. When used with a digital voltmeter, steady one nanovolt digits may be displayed, with a response time constant of less than a second. The input voltage stability of the A10 is very high, with the drift around a nanovolt per degree C. The input connectors are made from pure copper. The input impedance is very high, and is time dependent, determined by the loop gain.

Pressure Control Machine
EQ-6V / EQ-12V
-
The constant pressure device enables the stable supply of materials to the stuffing machine by keeping constant the pressure to the materials in the pipe fed from the pump to the stuffing machine side by air pressure. When the materials being fed from the pump, the surplus materials unnecessary to be stuffed shall be sent into the constant pressure cylinder. And when the constant pressure cylinder is full, the supply from the pump shall be stopped and then the materials in the cylinder shall be discharged into the pipe by constant pressure. Accordingly, it is unnecessary to synchronize the stuffing speed with the pump speed by every product. Also, the pressure shortagegenerated when the pump motor starts and the effect of pressure fluctuation in the pipe due to the changes of the speeds of the pump motor and stuffing machine can be minimized so that it is possible to supply stably the materials to plural stuffing machines.
