MINI PANEL MOUNTED CONTROLLERS

HANNA mini controllers are easy to use and allow accurate continuous monitoring and control of pH, ORP, TDS, EC, resistivity and level.

What it is 4-20mA output?

(4 to 20 MilliAmp) A point-to-point or multi-drop circuit mainly used in the process automation field to transmit signals from instruments and sensors in the field to a controller.

What type of signal does a 4-20mA output send?

It sends an analog signal from 4 to 20 mA that represents 0 to 100% of some process variable. As a current loop signal, 4-20 mA also powers the sensor transmitter on the same wire pair, and 4-20mA provides more resistance to interference than a voltage-based line.

What is a NEMA enclosure?

NEMA defines standards for various grades of electrical enclosures typically used in industrial applications. Each is rated to protect against designated environmental conditions. A typical NEMA enclosure might be rated to provide protection against environmental hazards such as water, dust, oil or coolant or atmospheres containing corrosive agents such as acetylene or gasoline.
