Dual Channel Vibration Transmitter Model ET-920 is a machine surveillance and measurement device which has two independent channel or universal accelerometer input of 100 mv/g. The transmitter shall provide milli amps signal (4-20),alarm and alert signal from relays for respective channel/sensor and dynamic signal from buffered terminal connectors provide in front side of the device. The casing is made of industrial grade ABS Nylon with accelerometer (2 nos) with necessary industrial cable –BELDON along with SS Sheathing (protection).
