What are 4 channel paperless recorders?
The paperless records collect data/calculated data in the internal storage system of the instrument on the basis of time, without consuming any commonly used recording facilities, such as paper, pen and ink. The stored data recorded in the instrument is displayed on the LCD screen after calculation and simulation. Paperless graphic recorder has many formats to display the data, such as, value display, bar graph display, curve display, history, alarm list, etc. The digital paperless recorder can accept universal signal inputs, such as the flow signal of the flow meter (4-20mA or frequency), the pressure signal of the pressure transmitter, the temperature signal of the thermal resistance (RTD) and the thermocouple, etc.
Signal types can be accepted by the 4 channels paperless graphic recorder
The data collected by paperless recorders can be: temperature, pressure, flow, liquid level, voltage, current, humidity, frequency, vibration, speed, etc.
It can accept current 4-20mA or 10 mA, 1-5V voltage, 0-5V voltage, 0-10V voltage, 20mV voltage, 100mV voltage, 100Ω resistance, PT100, Cu50, Cu53, thermocouple S, thermocouple R, thermocouple B, thermocouple K, thermocouple J, thermocouple E, thermocouple N, frequency ,etc.

4 channel paperless recorder Price
The price of 4 channel paperless recorder is determined by many factors.
First is the brand and model. For example, Yokogawa paperless recorder, Honeywell paperless chart recorder, VR06 paperless recorder, FUJI paperless recorder, Brainchild paperless recorder, Endress Hauser paperless chart recorder, Omega paperless chart recorder, paperless recorder model GX10 etc, these brands are not cheap. SILVER is provided by the paperless recorder factory in China. The price is cheap. SILVER has 4 channel paperless recorders in stock. The shipment is very fast and the price is very low.
The price of the recorder is also related to the size of the screen. The larger the screen size, the more expensive it is. For example, a 10.4” color paperless recorder is much more expensive than 3.5” .
Color screens are more expensive than monochrome screens.
The price of the 4 channels paperless recorder is also related to the functions, such as Ethernet, touch screen paperless recorders, current output, relay output, SD card and other functions, all affect the price of the paperless recorder. The price of SILVER 4 channels recorder starts at $200.
