Rate, frequency and speed panel meters

The meters and controllers on this page accept pulse inputs from such sensors as NPN, PNP or namur proximity switches, rotary encoders etc. All can be easily scaled to read in RPM, frequency, metres per minute etc..

Suited for these applications and more:-

• Engine speed in RPM
• Conveyor speed in metres per minute, feet per second etc.
• Production line output speed, such as items per hour
• Generator frequency, such as 40.000 to 70.000 Hz
• Any physical variable represented by a variable frequency

This page has 1 model for you to choose from:-

[INT-F]

[^] Model INT-F
The INT-F is a low cost yet highly flexible and easy to use 1/8 DIN scalable rate/frequency meter. It can also be used as a counter/totaliser with 1 or 2 input channels. It has a number of useful plug-in options which make it ideal for use in many control and monitoring applications.
Input connections	One input channel used. Excitation voltage output.
Input Signal	The meter can accept NPN, PNP, contact closure, 5V pulse, 24V pulse, low level AC and high level AC signals. Debounce filtering for contact inputs. Frequency range 0.03Hz to 50 000 Hz.
Excitation	24V DC up to 100mA
Digits	5 digits, 14mm high. Legible up to 7 metres away
Digit colour	Red or green
Scaling	Digital menu-free system. Floating point scale factors for precise scaling. No need to calculate scale factors - simply enter a typical input frequency and desired reading value and the meter will compute scale factor automatically.
Filtering	Adjustable 0 to 5 Seconds
Last digit Round-up	Selectable 1,2,5,10,20,50
User linearisation	not available on this model
