下一代紧凑型电子开关
The next generation of compact electronic switches

领先的控制产品制造商 Barksdale 宣布推出最新版本的 3000 系列 紧凑型电子开关。 该系列目前包括 电子温度和压力开关 （即将推出液位和流量模型），具有 320 度可旋转 4 位显示屏、多种配置和 EMI 保护。

Barksdale BTS3000 电子双温度开关 和 Barksdale BPS3000 双压力开关 提供三种方便的配置：双开关、带模拟输出的双开关（4-20 mA 或 0-10 V）或带模拟输出的单开关。 在一个紧凑的包装中，您会发现结合了三个分立元件（双压力开关、压力传感器和数字压力表）的压力开关或完全可编程的温度控制设备。

设定点和死区可通过用户友好的菜单轻松调整，其中迟滞可设置为其测量范围的 125%。 模拟传感器输出可从整个可调范围的 25% 扩展到 100%，并且外壳高度刚刚超过 4 英寸，直径远低于 2 英寸，BTS3000 允许紧凑的柜内安装。

大型 4 位 14 段 LED 角度显示屏美观且可从多个点清晰读取。 即使设备需要倒置安装，内部软件也能够将其显示屏旋转 180 度。 此外，320 度可旋转电气连接和显示外壳使安装更简单、更便宜和更通用。

具有 EMI 保护的压力和温度开关

BTS3000 温度开关 是要求精度、灵活性和长寿命的温度控制应用的理想解决方案。 它们通常用于机床行业、液压和气动系统、注塑机、冷却监控和电路、润滑系统、工程机械和汽车行业。

BPS3000 具有强大的 EMI 保护功能，可在当今存在 EMF 和大功率对讲机的工厂中实现稳定的输出。 此外，IP65/IP67 等级的外壳使该装置适用于最潮湿的环境，甚至完全浸没。

它适用于需要精密 压力控制 、灵活性和极长寿命的应用。 其中包括机床行业、工厂自动化、注塑机、润滑监控、泵和压缩机。 压力范围从 0 到 3 psi 到 0 到 9000 psi，绝对压力范围高达 150 psia。

提供多个过程连接作为标准，从 ?” NPT 到 7/16” SAE 仅举几例。 BPS3000 还通过分别提供 0 至 10 V DC 至 4 至 20 mA 的模拟输出信号来提供变送器功能。 可以在安装过程中设置可读范围，从而实现更大的灵活性。

The next generation of compact electronic switches

Leading control products manufacturer, Barksdale , has announced the latest release of their Generation 3000 Series of compact electronic switches. The range currently includes electronic temperature and pressure switches (with level and flow models due out soon) that feature a 320-degree rotatable 4-digit display, multiple configurations and EMI protection.

The Barksdale BTS3000 Electronic Dual Temperature Switch and Barksdale BPS3000 Dual Pressure Switches are available in three handy configurations: dual switch, dual switch with analog output (4-20 mA or 0-10 V), or single with analog output. In one compact package, you'll find either a pressure switch that combines three discrete components (dual pressure switch, pressure transducer, and digital pressure gauge) or a fully programmable temperature control device.

Setpoints and deadband are easily adjusted via a user-friendly menu where hysteresis can be set up to 125 per cent of its measuring range. Analog transducer outputs are scalable from 25 per cent to 100 per cent of the full adjustable range and, with a housing height just over four inches and a diameter well under two inches, the BTS3000 allows for tight in-cabinet installations.

The large 4-digit 14 segment LED angled display is aesthetically pleasing and allows clear readability from multiple points. Even if the unit needs to be mounted upside down, the internal software is capable of rotating its display 180 degrees. Plus, the 320-degree rotatable electrical connection and display housing makes for simpler, cheaper and more versatile installation.

Pressure & Temperature switches with EMI protection

The BTS3000 temperature switch is an ideal solution for temperature control applications requiring precision, flexibility and long life. They are commonly used in the machine tool industry, hydraulic and pneumatic systems, injection moulding machines, cooling monitoring and circuits, lubrication systems, construction machinery and the automobile industry.

The BPS3000 features robust EMI protection allowing for stable output in today's factories where EMF and high powered walkie-talkies are present. Additionally, the IP65/IP67 class rated housing makes this unit suitable for the wettest of environments, and even full submersion.

It is suitable for applications that call for precision pressure control , flexibility and extremely long life. These include in the machine tool industry, factory automation, injection moulding machines, lubrication monitoring, pumps and compressors. Pressure ranges are available from 0 to 3 psi up to 0 to 9000 psi, with absolute pressure ranges up to 150 psia.

Multiple process connections are offered as standard from ?” NPT to 7/16” SAE just to name a few. The BPS3000 also offers transmitter functionality by supplying analogue output signals 0 to 10 V DC to 4 to 20 mA respectively. The readable range can be set during installation enabling more flexibility.
