Описание
Там, где температуру процесса необходимо показывать на месте или в труднодоступных точках, а также требуется переключение электрических цепей, газоуправляемый термометр с контактами для коммутации находит своё применение.
Благодаря широкому разнообразию возможных исполнений газоуправляемые термометры модели TGS73 могут быть оптимально адаптированы к любому процессному присоединению или месту установки. В исполнении с регулируемым штоком и циферблатом корпус можно точно настроить под требуемый угол обзора.
В исполнении с контактной колбой (без непосредственного контакта со средой) измерение температуры и её переключение возможны даже при крайне малом диаметре трубопровода. Контактная колба предназначена для наружного монтажа на трубах и ёмкостях. При установке данного исполнения термометра необходимо обеспечить, чтобы контактная колба соприкасалась с местом измерения по всей своей длине.

Контакты для коммутации (электрические контакты сигнализации) замыкают или размыкают цепи в зависимости от положения стрелки измерительного показывающего прибора. Контакты для коммутации регулируются по всей шкале измерений. Стрелка прибора (стрелка фактического значения) перемещается свободно по всему диапазону шкалы независимо от настройки. Установленная стрелка может быть отрегулирована через окно с помощью съёмного ключа для настройки (установлен на кабельном разъёме). Контакты для коммутации, состоящие из нескольких контактов, также могут быть настроены на одну уставку. Срабатывание контактов происходит при перемещении стрелки фактического значения выше или ниже заданной уставки.
В качестве контактов для коммутации доступны магнитоупругие контакты с мгновенным переключением, индуктивные контакты и электронные контакты. Индуктивные контакты могут применяться во взрывоопасных зонах. Для срабатывания программируемых логических контроллеров (PLC) могут использоваться электронные контакты.

Вопросы и ответы
Какой диапазон температур измеряет TGS73?
Доступны многочисленные диапазоны: от −80 … +60 °C до 0 … +700 °C. Конкретный диапазон выбирается при заказе прибора.
Какой класс точности у прибора?
Класс 1 по DIN 16196 при температуре окружающей среды 23 °C ±10 °C.
Какие типы контактов доступны и чем они различаются?
Магнитные контакты мгновенного действия, индуктивные и электронные. Индуктивные контакты могут применяться во взрывоопасных зонах, электронные — для срабатывания программируемых логических контроллеров (PLC).
Можно ли применять TGS73 во взрывоопасных зонах?
Да, исполнения с индуктивными контактами предназначены для использования во взрывоопасных зонах и имеют сертификаты ATEX и IECEx.
Какое присоединение к процессу предусмотрено?
Доступны резьбы M18 x 1.5, M20x1.5, M24 x 1.5, G ½ B, G ¾ B, ½ NPT и ¾ NPT; электрическое присоединение — M20x1.5.
Из какого материала изготовлен шток и каковы его размеры?
Шток изготовлен из нержавеющей стали 316, длина — 200 мм, диаметр — 6,0 мм.
Возможно ли измерение без контакта со средой?
Да, в исполнении с контактной колбой (без непосредственного контакта со средой) измерение возможно даже при малом диаметре трубопровода; колба монтируется снаружи на трубах и ёмкостях и должна прилегать к месту измерения по всей длине.
Какая степень защиты корпуса?
Степень защиты IP65.

| Thermowell / Protection tube | In principle, the operation of a mechanical thermometer is possible without a thermowell / protection tube with low process-side loading (low pressure, low viscosity and low flow rates). However, in order to enable exchanging the thermometer during operation (e.g. instrument replacement or calibration) and to ensure a better protection of the measuring instrument and also the plant and the environment, it is advisable to use a thermowell / protection tube from the extensiveWIKA portfolio. → For further information on the wake frequency calculation of the thermowell / |
