概述

summarize

WZPK温度变送器是我公司推出的一款高性价产品，适用于多达十种的各型热电偶和热电阻信号变送。该产品使用24位Σ-△模拟前端，保证测量的高精度；完善的防浪涌、防反接设计，避免了工程应用中的误安装和误操作；增强的软件安全设计，包括低压监控复位、多任务调度优化等功能。WZPK全部采用进口元器件，保证较长的使用寿命和稳定性。为了便于大客户的长期备货，可使用USB通讯线进行组态设置，并且设置时无需外接电源。

WZPK temperature transmitter is a high cost product from our company, suitable for up to ten types of thermocouple and thermal resistance signal transmission. The product uses a 24-bit Σ-△ analog front end to ensure high precision measurement. Perfect anti-surge and anti-reverse design to avoid misinstallation and misoperation in engineering applications; Enhanced software security design, including low-voltage monitoring reset, multi-task scheduling optimization and other functions. WZPK all use imported components to ensure long service life and stability. In order to facilitate the long-term stocking of large customers, the USB communication cable can be usedfor configuration Settings, and no external power supply is required for setting.

三、接线方式

wiring mode

1号接线柱和2号接线柱分别为24V电源正负极，线路板带防反接功能。

The No. 1 terminal and No. 2 terminal are respectively the positive and negative terminals of 24V power supply, and the circuit board has anti-reverse connection function.

热电阻连接支持二线制、三线。连接方式如上图所示，实线为传感器引出线，虚线为短接线，需要用户自行用短导线连接（出厂时也可按客户需要在内部短接好）。

热电偶正极连接3号接线柱，负极连接4号接线柱即可。

The thermal resistance connection supports two wire and three wire. The connection method is shown in the figure above. The solid line is the sensor leadout line, and the dashed line is the short wire, which needs to be connected by the user with a short wire (it can also be short-connected internally according to the customer's needs).

The positive terminal of the thermocouple is connected to terminal 3, and the negative terminal is connected to terminal 4.
