Analog Modem Routers are equipped with two external modem ports (RS 232 Serial) that allow connecting two modems/ISDN to the same ISP or two different ISP's.

Analog Panel Meters are instruments that measure variables such as pressure, flow, temperature, speed, current and voltage. They display values on a dial with a moving pointer or needle. Analog panel meters are available with one or more channels and measure one or more variables in different units. Analog panel meters measure single or three phase power. Analog panel meters feature a range of measurements such as 0 - 4 mA or 0 - 10 VDC.

Analog Pressure Gauge consists of two circular shaped, convoluted membranes sealed tight around their circumference. The pressure acts on the inside of the capsule and a pointer indicates the generated stroke movement. Pressure gauges with capsule elements are more suitable for gaseous media and relatively low pressures. It combines both a chemical seal and a pressure gauge into one unit. A metal pushrod welded to the top of the diaphragm transmits the deflection of the diaphragm to the linkage.
