 YMC8601：Single Channel Dynamic Strain Amplifier Frequency response range is as wide as DC to 100 kHz; Strain amplifier mode provides a range of ± 100,000με; Noise referred to input is low despite the wide bandwidth and high gain capabilities. Balance adjustment is possible up to ±1000μ (equivalent to a resistance deviation of 2%). RANGE, L.P.F., VERN and BAL settings are saved in non-volatile memory. Digital indicator; Powerful low-pass filter provides the attenuation characteristic of -24 dB / oct. |
 YMC8603 Multi-channel General Purpose Dynamic Strain Amplifier Flexible Modular: 4, 6, 8 channels; Low cost; LED Digital indicator displays output voltage value; L.P.F., Gain, Bridge Voltage switchable; Long cable Long wire automatic compensation; Auto or Manual banlance; Suitable for measuring general strain testing. |
