A kit for measuring the length of a workpiece on a production belt. The kit includes a CI4 pulse counter, a 360 imp/rev incremental encoder, an adjustable arm for the encoder, and a rubber-coated measuring wheel.
A kit for measuring the length of a workpiece on a production belt. The kit includes a CI8 pulse counter, a 360 imp/rev incremental encoder, an adjustable arm for the encoder, and a rubber-coated measuring wheel.
Professional, temperature controller with two NTC sensors included. The control is based on the on/off (ON-OFF) method with adjustable hysteresis. The controller is characterized by two temperature measurement channels (T1 main sensor, T2 auxiliary sensor), control output R1 (16A) and auxiliary output R2 (5A). They are used both in refrigeration equipment and installations, and in heating processes where additional temperature control is needed. The controller has a dimension of 76x35mm and is adapted for mounting in a board in a 70x28mm hole, using mounting brackets. The maximum thickness of the board must not exceed 22mm.

Thecontroller maintains the set temperature with the set hysteresisthrough the relay output. Temperature measurement is done through the chamber temperature sensor. The controller can operate in two modes of temperature control:
Example: Set temperature (X): 80°C, Hysteresis (h): 1°C In HEAT mode, the controller starts heating when the temperature of sensor T1 is lower than the set temperature - hysteresis [X-h], and stops heating when the temperature on the chamber sensor is higher than the set temperature + hysteresis [X+h].
Example: Set temperature (X): -10°C, Hysteresis (h): 1,4°C In COOL mode, the controller starts cooling when the temperature of sensor T1 exceeds the set temperature + hysteresis [X+h], and ends cooling when the temperature at the chamber sensor is lower than the set temperature hysteresis [X-h].

Audible temperature alarm
NA8820A + controller has a function of signaling exceeding of the temperature above the assumed T max value and below T min. For parameters :
U52 : Delay for audible temperature alarm.
U53 : After power supply , delay for the first alarm signal (0=function disabled).
U54 : T max Value that is added to the temperature task causing an audible top alarm if : T read >= T set +U54
U55 : T min Value that is added to the temperature task causing an audible low alarm if : T read =< T set +U53
Below is an example of use:
fig Example of use - Audible temperature alarm
When NO or NC contacts No.10 and No.7 are shorted or opened while the controller is operating, the symbol "iA" will be displayed on the screen to indicate that the controller is locked in response to an external warning signal, which will cause R1 output to open and the buzzer to sound. Manual contacts, e.g. main switch or other external sensors, e.g. inductive, float, limit, optical, audible, etc. can be used to short circuit or open.
Parameters for input D1 (U60):
0: (off) NO normally open state (contacts 7 and 10 must be shorted to trigger the alarm).
1: NO - when shorted, locked until the "P" key is pressed
2: NO - unlocked automatically after opening the contacts normally closed state NC (to trigger the alarm it is necessary to open contacts 7 and 10)
3: NC - locked after opening until the "P" key is pressed
4: NC - unlocked automatically after shorting the contacts
U61: Delay for external alarm input D1
