This is a dual set point temperature controller with two output relays and a single PT100 input. Each set point controls its own output relay.It can be configured as a high / low limit, heating / cooling, two stage heating (or cooling) controller or as a heating or cooling controller with alarm. The main advantage of this controller is the calibration which has been done digitally through software. So there is no need to do the calibration every year and the setting cannot be altered as it is protected with a password. Digital display, microprocessor based design, electrical noise-resistance even in a rough industrial environment and user friendly key operations are the main features of this instrument. How to set the temperature The temperature can be set by pressing the  key which will show TP1 on the main display. Press the  key which will show the current set temperature of TP1 and change the parameter through  /  key. Press  key again to save the parameter of TP1 and then TP2 will appear on the main display. The parameter of TP2 can be set by following the instruction as of TP1. After setting TP1 and TP2 the temperature controller can be restarted by using the  key.

Temperature Range : 0-300 degree.

We manufacture different types of temperature sensors as per the specifications of the customer by using PT100 sensing element and maintain international quality. The element of PT100 sensors has been imported from Germany and the SS rod is made up of 316 stainless steel material, which enables it to withstand a high pressure vessel. The sensor has been designed in such a manner that it is well suited for temperature measurement in any industrial environment, especially around motors, generators and other high voltage equipment. The range of the PT 100 sensor varies from 0-400 degree.

Type : Simplex and duplex.

The TC 09 is a proportionate temperature controller with dual display and digital calibration. This proportionate controller decreases the average power supplied to the heater as the temperature approaches set point. This ensures that it will not overshoot the set point and maintain a stable temperature. This proportionate temperature controller maintains a stable temperature due to the inbuilt proportionate band which has two fixed parameters and these are PB and PT. PB is set at 5 degrees and PT is fixed for 30 seconds. If the set temperature is 100 degrees, the PB & PT will activate at 95 degrees. At this point, the ON time of the heating is 60% of PT and OFF time is 40%. This means an ON period of 18 seconds and off time of 12 seconds. When the temperature reaches 99 degrees, the ON time of the heating will be 40% and off time 60%. The controller has two displays. The first one indicates actual temperature and other indicates set temperature. The main advantage of this controller is the calibration which has been done digitally through software. There is no need to calibrate the controller every year and nobody can alter the setting as it is protected with password.

Temperature Range : 0-300 degree.

The TC-10 is an ON /OFF temperature controller with dual display and digital calibration. This instrument has been designed with the latest integrated chip technology which could help to minimize the components of the instruments. So the breakdown rate of the instruments due to component failure has been reduced to zero. The calibration and linearity of the temperature is controlled through software and so the mechanical preset for the temperature calibration has been eliminated. There is no need to calibrate every year as it is guaranteed for at least five years. The calibration cannot be altered by anyone on the site as it is password-protected.

Temperature Range : 0 - 300 degree.

It is a multi function ON / OFF delay timer which can be configured as per the specification of the application. The user friendly key operation enables to switch over to ON delay or OFF delay. The timer has two selectable time ranges which are second and minute .The duration of the ranges vary from 1 second to 999 minutes. The design of the timer is in such a way that it works smoothly in any rough industrial environment.. Memory back up in case of power failure is the main advantage of this instrument. Down counter, digital display, LED indication for the relay status and latest integrated chip technologies are the main features of this timer. The timer can be restarted either by pressing  key or switching ON the input supply. It is a multi function ON / OFF delay timer which can be configured as per the specification of the application.

The timer can be restarted either by pressing  key or switching ON the input supply. How to change the mode of the timer Switch ON the timer by pressing the  key, which will display the default / current mode on main display and change the same by pressing  /  key. Select the desired mode and press the  key to save. Details of different modes are given below:- TT 0: ON delay seconds. TT 1: ON delay minutes. TT 2: OFF delay seconds. TT 3: OFF delay minutes. How to change the parameter of the timer Time can be set by pressing  key which will show the current mode on the main display. The parameter can be set by pressing  and  /  keys. After changing the parameter press  key again to save modified parameter.  

This timer is specially developed to control the direction of the motor such as forward, reverse and pause time in between the directions. It is basically used in yarn dyeing, lab dyeing and other machines in which the direction of the motor is to be controlled.The main advantage of the same is that it eliminates all electrical hardware to create a multi- functional timer in the control panel due to which the size of the control panel is minimized. Digital display, user friendly key operations, separate relay output for each direction and microprocessor based design are the main features of this instrument. All set parameters will be saved during the power failure. The timer always starts with the pause time which ensures the safety of the pump. The maximum limit for the forward and reverse setting is 99 minutes while the downtime of the motor is 99 seconds. How to change the parameter The time can be set by pressing  key which will show forward (For) direction on main display. If you want to change the parameter of forward direction then press  key followed by  /  key. After changing the parameter press  key again to save the parameter. Similarly reverse direction (rEU) and motor off time (dt) can be set. The timer can be restarted by using  key.
