Digital panel meters for pulse/frequency display
Mike Edwards
Products analog AutomationDirect ProSense temperature
ProSense digital panel meters in 1/32 and 1/8 DIN sizes from AutomationDirect feature IP65-rated meter faces, simple menu-driven pushbutton configuration, and accept a wide variety of process inputs.
Red, green or amber, 4 and 5-digit LED displays are available depending on model. All ProSense panels offer selectable decimal point location. Available input options include analog, temperature, AC/DC current and voltage, and pulse/frequency inputs.
The new pulse/frequency input models are said to offer a simple, low cost digital display for frequency, tachometer, and rate applications.
These pulse/frequency units accept input from AC voltage, magnetic sensors, NPN/PNP sensors, NAMUR sensors, TTL/24V encoders, or switched contacts, and provide selectable sensor excitation voltages.
Process display options include analog process signals, load cell, or potentiometer inputs, and temperature inputs in either °F or °C from RTDs or thermocouples. Inputs from electrical parameters such as AC or DC voltage and amperage, as well as pulse and frequency inputs, are also available.
Available output options include alarm relays, analog signal re-transmission, and sensor excitation voltage.
