Abstract
Tekanan merupakan besaran fisis dalam sistem AC (Air Conditioner) yang nilainya penting untuk diketahui karena terdapat perubahan fasa yaitu mengembun dan menguap. Kerja kompresor berpengaruh pada perbedaan nilai tekanan baik di saluran tekan maupun saluran hisap kompresor, sehingga perlu dilakukan monitoring untuk mengetahui perbedaan tekanan. Output sensor pressure transmitter 4-20 mA diubah menjadi tegangan 1-5 volt dengan rangkaian pengkondisian sinyal kemudian ke pemroses sinyal yaitu Arduino dengan program tertentu sehingga dapat ditampilkan. Pada monitoring menggunakan sistem data logger sebagai recorder nilai tekanan yang disimpan dalam memory micro SD. Hasil uji sensor dalam sistem yaitu nilai tekanan pada saluran tekan 11,53 Bar dan saluran hisap 7,24 Bar dengan tekanan keadaan awal saat AC belum bekerja yaitu 24 Bar dan 16 Bar. Karakteristik statik dari TPS20 G2Z8F8-00 yaitu resolusi 0,001, error 5,608333 kg/cm2 , akurasi 0,943916667 dan presisi 0,881053831 dengan spesifikasi standart deviasi 0,220918649 kg/cm2 , dan Uexpand sebesar 2,61365242 kg/cm2 . Karakteristik statik ADZ – SML 10.0 yaitu resolusi 0,001, error 0,462626146 kg/cm2 , akurasi 1,462614583 dan presisi 0,783478286 dengan spesifikasi standart deviasi 0,09077712 kg/cm2 , dan Uexpand sebesar 4,444853586 kg/cm2 .

Abstract Pressure is the physical quantities in the air conditioning system (Air Conditioner) whose value is important to note because there is a phase change that condenses and evaporates. Compressor effect on the difference in pressure in both the channel tap and compressor suction channels, so it needs to be monitored to determine the pressure difference. Pressure sensor output 4-20 mA transmitter is converted into a voltage of 1-5 volts to the signal conditioning circuit and then to a signal processor that is Arduino with a particular program so that it can be displayed. In using the monitoring system as a data logger recorder pressure value stored in the micro SD memory. The test results of sensors in the system that is the pressure value on the channel press 11.53 Bars and suction channels with the pressure of 7.24 bar initial state when AC is not working is 24 bar and 16 bar. Static characteristics of TPS20 G2Z8F8-00 ie 0,001 resolution, error 5.608333 kg / cm2, accuracy and precision 0.943916667 0.881053831 0.220918649 with specification standard deviation kg / cm2, and Uexpand of 2.61365242 kg / cm2. ADZ static characteristics - ie 10.0 SML 0,001 resolution, error 0.462626146 kg / cm2, accuracy and precision 1.462614583 0.783478286 with specification standard deviation 0.09077712 kg / cm2, and Uexpand of 4.444853586 kg / cm2.
