PID Controller
Radix has a large selection of mid-range and low-cost Programmable Temperature/Process Controllers. Our controllers accept a wide variety of inputs from RTD sensors, thermocouples as well as linear inputs such as such as 4 - 20 mA, 0 - 20 mA, 0 - 50 mV, etc. Large LED displays and LED lights on the controller indicate process variable, setpoint, and relay, communication status.These are easily visible to operators from a distance. Operators can easily program setpoints, alarms, control outputs on the controller via membrane keys on the front of the unit to trigger heating, cooling and high-low alarms. Our Programmable Temperature Controllers retransmit isolated current (4 to 20 mA, etc) or voltage (0 to 10 V, etc) outputs to protect downstream equipment and devices (such as PLCs) from damage. These Controllers are also available in flameproof versions. Radix also offers full-featured PID controllers, differential controllers, blind temperature controllers, etc.

Temperature Transmitters
Head Mounted Transmitters convert low-level input signals from field sensors into a proportional 4 - 20 mA output that is ideal for driving other control instrumentation.
Few models of Radix temperature transmitters also has signal isolation and also comes with the HART communication options. Radix temperature transmitters convert a variety of input signals into a scalable 4 to 20 mA analogue output signal. The transmitter converts 8 types of thermocouples (B, E, J, K, N, R, S, T), RTDs (Pt100, Pt500, Pt1000, Cu53, Ni100, Ni500, Ni1000) resistance (0 up to 400Ω, 2000Ω or 5000Ω) and a wide range of linear voltage inputs (-10-75 mV, -100-100 mV, -100-500 mV, -100-1000 mV). Few head mount temperature transmitter has an internal temperature sensor for active temperature compensation. The SCC641/631 is in range high quality temperature transmitter, with an efficacy loss of less than 0.05% per year.
Signal Isolators
Quality measurement and good equipment are very important parameter to achive Signal integrity. However, even with the best equipment, signals can be of inferior quality if the equipment is not properly installed or it is not protected by signal isolators / signal conditioners.
Radix design competency in signal isolation is one of the finest to be found. Radix signal isolators are an outstanding combination of accuracy, frequency response and signal handling. Choose from loop-powered isolators which require no external power supply and have very low loop drops, 3-port signal isolators which not only isolate input signals, but also act as signal multipliers and multiply signals to send to multple field instruments. Some of our signal isolators are HART compatible for effortless two-way field communication, that is achieved through superimposition of digital communication on top of the 4-20 mA signal.
Signal isolation devices are use to eliminate ground loop errors caused by noise (ground) and other such signal interference problems.
Signal isolators use one of many electronic methods to interrupt the connections between two grounds while passing the correct signal with little or no loss of accuracy. Without a way for ground currents to flow, these currents can't induce signal errors caused by ground noise.
