مقدمه
HBLT-wire یک سنسور خازنی برای اندازه گیری سطح مبرد منی NH3 در سیستم های صنعتی یخچال است. سنسور یک سیگنال خروجی از 4 تا 20 میلی آمپر دارد که با 0 و 100 درصد متناسب است. سیگنال خروجی آن 4 میلی آمپر برای یک ظرف خالی است و 20 میلی آمپر برای یک ظرف کامل. کابل HBLT را می توان در طول به کاربرد فعلی تنظیم شده است. عنصر سنسور شامل یک سیم فولادی 2 میلی متر و همچنین یک لوله تفلون است. دو بخش با طول 4 متر ارائه می شود و می تواند کوتاه شود با برش های مورب یا انبردست های دیگر. اتصال HBLT به همراه کنترل کننده HBLT-C1 برای کنترل پمپ ها می تواند مورد استفاده قرار گیرد.
جزئیات فنی
- سیم سنسور قابل انعطاف، قابل تنظیم به طول 600 تا 4000 میلی متر است.
- طراحی قوی و قابل اعتماد با یک سیگنال خروجی استاندارد 4-20 میلی آمپر
- طراحی شده برای صنعت تبرید - حداکثر. فشار تا 100 بار.
- طراحی تقسیم شده که باعث می شود حسگر به راحتی نصب و سرویس شود. بخش الکترونیکی به راحتی می تواند از طریق بخش های مکانیکی از بین برده شود.
- کالیبراسیون ساده برای طول مشخص شده.
- خروجی هشدار را می توان در محدوده 10٪ تا 100٪ تنظیم کرد
- طراحی فشرده که هزینه های حمل و نقل را کاهش می دهد.
- می تواند برای برنامه های کاربردی دریایی مورد استفاده قرار گیرد، زیرا اندازه گیری توسط تماس با سطح فلز لوله سرریز تاثیر نمی گذارد.
- اندازه گیری مبرد NH3 و HFC (R22، R134A، R404A، R410A، R507، R717 و R718).

Connection diagram

The sensor can be programmed to either emit a linear signal, which is identical to the tank level, or to regulate a valve for the purpose of obtaining the same level in the tank (float valve).

کاربرد
Use of HBLT-A2
When using a level sensor for measuring Ammonia in a compact plate and shell heat exchanger or other systems with turbulent conditions, we have new recommendation based on recent experience:
For Stand-pipes with stable conditions (smooth changes in the level):
Use a HBLT-Wire or a HBLT-A2 or HBLT-A1 rod-style sensor.
For Stand-pipes with turbulent conditions (a lot of turbulence, cooking, foaming, liquid from the top):
- Use a HBLT-A2 or HBLT-A1 rod-style sensor, or
- Use only a HBLT-Wire sensor when you have it mounted in an inner guide-tube of e.g. DN25 as
illustrated. The guide-tube will dampen the turbulence and the foaming and you will have a good
measurement. - If HBLT-Wire sensor is already mounted under these conditions WITHOUT a guide-tube, do
eventually set the filter time function between 60-120 seconds to dampen the signal from the
turbulent conditions.
For tank/drum installation:
- Use a HBLT-A2 or HBLT-A1 rod-style sensor, or
- Use only a HBLT-Wire sensor when you have it mounted in an inner guide-tube of e.g. DN25 as
illustrated. The guide-tube will dampen the level and the foaming and you will have a good
measurement. - If HBLT-Wire sensor is already mounted under these conditions WITHOUT a guide-tube,
do eventually set the filter time function between 60-120 seconds to dampen the signal from the
turbulent conditions.
For Alpha Laval U-turn evaporator:
- Use a HBLT-A2 or HBLT-A1 rod-style sensor.

HBLT/C-A2, here’s a cable connection directly to a modulating fluid valve
such as Siemens MVS661, this will save installations cost because there is built
in a level controller in the sensor head.
