structural design techniques applied in astronomical instruments
Ground-based and Airborne Telescopes VII, 2018Co-Authors: Alejandro Farah, R Langarica, A M Watson, Jorge Fuentesfernandez, Salvador Cuevas, Fernando Angeles, Silvio J Tinoco, Jaime Ruizdiazsoto, Carlos Tejada, F QuirosAbstract:We present in this article some of the techniques applied at the Instituto de Astronomia of the Universidad Nacional Autonoma de Mexico (IA-UNAM) to the mechanical structural design for astronomical instruments. With this purpose we use two recent projects developed by the Instrumentation Department. The goal of this work is to give guidelines about support structures design for achieving a faster and accurate astronomical instruments design. The main guidelines that lead all the design stages for instrument subsystems are the high-level requirements and the overall specifications. From these, each subsystem needs to get its own requirements, specifications, modes of operation, relative position, tip/tilt angles, and general tolerances. Normally these values are stated in the error budget of the instrument. Nevertheless, the error budget is dynamic, it is changing constantly. Depending on the manufacturing accuracy achieved, the error budget is again distributed. That is why having guidelines for structural design helps to know some of the limits of tolerances in manufacture and assembly. The error budget becomes then a quantified way for the interaction between groups; it is the key for teamwork.

Rancang Bangun Alat Ukur Kelajuan Udara Tipe Thermal Terintegrasi Termometer Udara Berbasis Sensor LM35 dan PT100
Universitas Negeri Yogyakarta, 2017Co-Authors: Laila Katriani, Subroto Subroto, Asri Setyaningrum, Widi Sulistia NAbstract:Penelitian ini bertujuan untuk merancang bangun alat ukur kelajuan udara tipe thermal yang terintegrasi termometer udara menggunakan sensor LM35 dan PT100. Penelitian dimulai pada bulan Mei s/d Oktober 2016. Penelitian dilakukan di Laboratorium Elektronika dan Instrumentasi Jurusan Pendidikan Fisika Universitas Negeri Yogyakarta. Rancang bangun alat ukur kelajuan udara ini terdiri dari dua tahapan yaitu, perancangan perangkat keras (hardware) dan perancangan perangkat lunak (software). Perancangan perangkat keras terdiri dari perancangan sensor (LM35 dan PT100), perancangan IC LM317, perancangan pengolah data dan display. Perancangan perangkat lunak menggunakan bahasa C. Berdasarkan hasil pengujian yang telah dilakukan didapatkan bahwa keluaran sensor LM35, yaitu tegangan sebanding dengan perubahan temperatur, yang memiliki sensitifitas sebesar 0,009 volt/ºC dan tegangan keluaran awal dari sensor pada saat temperatur 0 ºC sebesar 0,041 volt. Keluaran sensor PT100, yaitu resistansi sebanding dengan perubahan temperatur yang memiliki sensitifitas sebesar 0,391 Ω/oC dan resistansi keluaran awal dari sensor pada saat 28 oC sebesar 100,8 Ω. Persen error dari pengujian alat ukur kelajuan udara tipe thermal sebesar 4%. DEVELOPMENT OF THERMAL TYPE ANEMOMETER INTEGRATED WITH AIR THERMOMETER USING LM35 SENSOR AND PT100 SENSOR This research aimed to design a thermal type anemometer integrated with air thermometer using Lm35 sensor and PT100 sensor. The study began in Mei until Oktober 2016. The study was conducted at the Laboratory of Electronics and Instrumentation, Department of Physics Education, State University of Yogyakarta. The design of the thermal type anemometer consists of two stages, namely, the design of the hardware and software design. Hardware design consists of a sensor system design (LM35 and PT100), LM317 design, system design for data processing and display. Software design using C language. Based on the results of tests that had been done, shows that the sensor output LM35, whic is voltage is proportional to temperature changes, which had a sensitivity of 0.009 volts / ºC and initial output voltage of the sensor when the temperature reach 0 °C is 0,041 volts. PT100 sensor output, which is resistance is proportional to temperature changes, which had sensitivity of 0.391 Ω/oC and initial output resistance of the sensor when temperature reach 28 °C is 100,8 Ω. Error percent of thermal-type air speed measuring instrument testing is 4%
