The Digital Pressure Controller accept input RTD, Thermocouple, Voltage , Current.  The Controller   suitable  for  Temperature ,Pressure, Humidity,  Level,  Flow , Tachometer, Voltmeter,  Ammeter . The input Is passed  through suitable filters to  eliminate unwanted  signals. Low Thermal drift operational amplifier  ensures good  stability.   Calibration Point can be set very accurately.  TMPC are available in many models.  When Indicate” 1” sensor is open condition . The instrument is housed In a compact sheet metal/Plastic case .  AC Mains  or    DC Voltage Operated Cold junction compensation is standard feature in Thermocouple input.
                              Tempsen also offers multi point indicators and multi zone indicator  like level

Temperature, Humidity, pressure, flow  or all zone temperature or humidity as your requirement of application. Large display (1”,2”,4”) indicator is available. The controller is compact size, priced very competitive. The unit can be draw from the front for Easy servicing. Product Quality Certified.
Tempsen THTT Humidity Temperature Transmitter is development in HVAC transmitters for relative humidity, temperature This Product utilizes humidity  sensor  capacitor   (HS1101,France Humirel) And   Temperature   sensor   (LM-32 ,America)   with characteristics of
Stable ,High accuracy , quick response ,good crossing-over and it also Use  craftwork of SMD, and so own   extremely small body , stable and  Reliably performance. The quality guarantee time is 12 months.Many useful functions can be activated with the Data logger with PC Base software There Are more  model  only temperature, only humidity output, humidity with
temperature output.

               Tempsen also offers Humidity  Temperature Jumbo Indicators, Recorder and PC
Based  data  Logging  system , Paper less Recorder  as your   requirement   of application. Large display (1”,2”,4”6” ) indicator is available.

solar track controller

Tracker :
 Tracker Principle:controls azimuth angle according to astronomical sun positioning
 Tracking axis:single axis
 Size:170mm x 120mm
 Input voltage:12VDC
 Enclosure IP65 ABS grade
 Termination:IP65 graded ABS glands – 2 nos
 Output:12V output to actuator up to 20A load
 Resolution:0.1 degrees
 Axis angle:settable up to +/‐ 60 degrees
 Control action:automatic closed loop using inbuilt inclinometer for angle feedback
 Display:16 x2 LCD display
 Timing:Inbuilt using highly accurate RTC with independent battery backup
 Accuracy:< +/‐1 degrees
 Safety features:a. Reverse polarity protection
  b. Over current protection
  c. Voltage spike suppression
  d. over current drain protection against mechanical failure of the actuator
system *
 ** The unit has an inbuilt time limit for the on time of the actuator fixed at approximately 2.5 minutes.
This is to ensure that if the actuator fails to move the panel to the required target angle for more than
2.5 minutes, the unit turns off the actuator load to preserve battery life and indicates “mech failure” for
3 seconds on the LCD display before skipping to the next target angle.
  
 
Charger :
 Input:Photovoltaic (PV) Panel or equivalent DC voltage source
 Output:To 12V,7.5AH Sealed Lead acid Battery
 Charging protocol:3-stage intelligent CV/CC charging profile
 Boost Voltage:14.4V DC
Boost current limit 1.0A
 Equalisation voltage:14.4V
 Equalization threshold current:0.01C (0.07A)
 Trickle voltage:13.5V
 Trickle current limit:0.4A
 Low battery threshold:10.8V
