乌克兰采购需求：线性热传感 (LHS) 电缆 - LHS 电缆、分布式温度传感 (DTS) 系统、光纤线性热检测 (LHD) 系统、光纤热探测器、数字 LHD 电缆

I'm looking to get a quote for a temperature measurement system that will serve dual purposes: monitoring the shopping galleries in a trading center and overseeing our main heat pipelines to detect any thermal leaks. Specifically, I'd like to know the price for a controller set and four rolls of 500-meter optic fiber cable. Could you provide details on the pricing and availability for these items? Additionally, any insights into compatibility or recommendations for optimal setup would be greatly appreciated, as we're aiming for an efficient and reliable system. Thanks!
