H8040N

LINEAR HEAT DETECTION (LHD)

(68°C, 155°F Nominal)

General

The siemple and proven technology of digital Linear Heat

Detection (LHD) cable, makes it a product of choice for

difficult and challenging applications where other

technologies struggle to work.

With it’s ease of installation and low maintenance it also

provides a cost effective solution where project

expenditure requires to be kept at a minimum.

The sensing cable is formed from a pair of twisted steel

conductors each with temperature sensitive insulation

and then an overall Nylon outer sleeve. When the

temperature sensitive insulation reaches it’s

predetermined alarm temperature the two conductors

short together providing the digital or switched signal.

The cable can be connected to any unit capable of

monitoring a switched signal, i.e. Conventional fire

panel, addressable switch monitor unit or PLC.

The nylon outer sleeve of the H8040N offers good

chemical and water resistance, allowing it to be

deployed in harsh and dirty environments.

Simple digital switch operation

Continuous sensing along the total

length of the element.

Fixed alarm temperature. Unaffected by

changes in ambient temperature.

Compatible with switch monitoring units

and conventional alarm panels.

Suitable for use in Hazardous areas

using safety barriers.

Chemical & water resistant

Rugged and durable construction.

Simple maintenance free installation.

Small diameter and bend radius.

美国7家保险公司近日向丰田汽车提起诉讼，试图追偿在丰田汽车事故中赔付的保险金。 保险公司起诉称，在丰田汽车突然加速导致的725起汽车事故中，事故原因是由于丰田汽车没有安装刹车优先系统。 丰田发言人CelesteMigliore表示：“任何关于丰田汽车因自身存在缺陷导致汽车突然加速的指控都是毫无根据的。” 对丰田提出追偿诉讼的保险公司有美国汽车保险公司、消防员基金保险公司、美国国家担保公司、Ameriprise保险、财产意外保险公司、车主相互保险公司和美国五金相互保险公司。 不久前，丰田在一起诉讼中向雷克萨斯车祸的受害人家属支付了1000万美元，以达成庭外和解。 处于天津市东丽区津塘公路245号的东联汽车用品中心将要重开。天津市东联汽车用品中心专营汽车精品、汽车内饰改装、高档精美饰品。据编辑了解到，这时店内正在为重开做紧锣密鼓地准备工作，期望能够给广大车迷带来一个更为新鲜的体验表示。 此外，店内还可以为全品牌车辆配备汽车高档用品编辑，包括音响、防爆膜、轮毂轮胎、真皮座椅、导航等等，上海道夫自动化仪表工程有限公司,道夫自动化仪表工程,提高车辆美观、实用、舒适度；并未车主的爱车进行内饰、外形整体翻新，售前和售后服务相结合，确保到店客户享受到更为完善的服务品质报道。 　　防爆专业人才的匮乏是阻碍防爆行业发展的重要因素，我国防爆行业与其他安防行业相比，人才缺乏的矛盾尤为突出，原装进口H8040N LHD哪家好,正宗火警探测、报警设备生产商，全行业按从业人员比例，原装进口H8040N LHD哪家好,正宗火警探测、报警设备批发，原装进口H8040N LHD哪家好,优质火警探测、报警设备感温报警器，专业技术人员占从业人员的比例不到十分之一，有的企业仅为百分之几。凝聚人才、尊重人才、用好人才是企业锻造优秀员工团队和提升核心竞争力的关键因素。市场竞争说到底是人才的竞争。企业引不来、留不住人才，会严重影响防爆监控企业的产品研发，也会阻碍防爆企业的发展。缺乏专业技术人员，导致企业整体发展进度缓慢，也影响了防爆监控行业的技术进步。
