KRIWAN DELTA-P2 Differential oil pressure cut out (Bitzer Part no. 34731911 / 34731811)
Made in Germany
Specification:
Bitzer Part no. 34731911 / 34731811
Supply AC 50/60Hz, 115-230V, -15…+10%, 3VA
Ambient temperature range: -30°C – +70°C
Relay AC 240V.max.2.5A, C300
Features:
An adequate oil supply is very important for the operating life of a compressor. Lack of lubrication e.g. due to oil shortage can lead to serious damage of bearings and sliding surfaces.
KRIWAN DELTA-P2 Differential oil pressure cut out is suitable for Bitzer reciprocating compressors with integrated oil pump. It can be integrated into bearing cover for monitoring the oil pressure.
KRIWAN OLC-D1 Level Control (Bitzer Part-No. 34794901)
Made in Germany
Specification:
Bitzer Part-No. 34794901
Supply AC 50/60Hz, 230V, ±10%, 3VA
Ambient temperature range: -30°C – +60°C
Relay AC 240V.max.2.5A, C300
Features:
Level monitoring
The OLC series consists of a screw-in prism unit and an optical level detection device. The prism is installed in the compressor or the vessel and is not included with the OLC. The level detection device can be replaced without opening to the compressor or the vessel. Detection of the level is via infrared light. There is a built-in monitoring system for correct installation.
Oil level monitoring in compressors
The OLC series are used for contactless oil level monitoring in compressors in order to safeguard sufficient lubrication of the internal mechanics.
As the refrigerant can be absorbed by oil, fluctuation of the oil level in the compressor is common in refrigeration systems and thereby oil levels need to be monitored.
OLC-D1 is for screw compressors and opens the relay after 5 seconds delay.
Level monitoring in vessels
The OLC-D1 is meant for level monitoring in vessels and does not have the operation recognition input, D1.
The OLC-D1 releases the relay if the level is too low and activates the relay if the level is valid. There is a 5 seconds time delay between switching the relay.
It is widely used for refrigerant control of mass production equipment such as indoor air conditioners, cabinet air conditioners, and vending machines.
The body portion and the coil portion can be packaged separately for delivery.
當空氣流量變化時，此開關能夠檢測壓差的變化（動
壓或通過固定節流圈的壓降）。由兩個傳感孔檢測
到的壓差，作用於壓差開關薄膜的兩側。用彈簧承托
的薄膜移動並啟動開關。 P32系列也可用於探測微正
壓，只需使用高壓連接端而不用使用低壓連接端。若
探測真空時，便只需使用低壓連接端，而高壓連接端
不接，直接接通大氣。
特點
易讀的設定點標度
範圍寬 (1~125mm水柱.)
偏差小 (最低1mm水柱)
接線空間大
多種安裝配件的型號可供選擇
應用
這種壓差（差動）開關是用於感應空氣流動，空氣壓
力或空氣壓差，典型的應用包括：
探測過濾器阻塞狀態
探測空調盤管結霜狀況或除霜週期的開始時間
檢測暖風或通風管內的風流狀態
作為變風量空調系統的最大風流控制器
