VAC定位器V200EX系列介绍
The V200EX is referred to as an “Explosion Proof” unit, due to the addition of the special rated and approved Ip module for hazardous locations. For rated areas of a plant where FM-CSA-Atex, Class1 Div. II or EEx (and other) approvals are required, this EX positioner product will meet those application specifications. This EX, 4-20 mA module can be specified at the time of order or converted in the field. They operate just like any other electropneumatic positioner, but the housing is designed to meet these stringent classifications. This EX module mounts directly to the V200P base positioner with a short adapter plate that supplies air pressure in the back side of the plate, which internally converts this pressure via a 4/20 mA signal, to a 3-15 psi signal back into the positioner signal diaphragm chamber. Not to be confused with Nema classifications (7 or 9) these FM-CSA, -ATEX, etc. area classifications/approvals are accompanied with the appropriate certificate documentation. For position feedback VAC offers a special third-party mounting adapter that allows for EX feedback mounting directly to the unit, eliminating clumsy linkage arms and complicated mounting.
V200EX 被称为“防爆”装置，因为它添加了用于危险场所的特殊额定和批准的 Ip 模块。对于工厂的额定区域，FM-CSA-Atex，Class1 Div.需要 II 或 EEx（和其他）认证，此 EX 定位器产品将满足这些应用规范。该 EX，4-20 mA 模块可以在订购时指定或在现场进行转换。它们的操作与任何其他电动气动定位器一样，但外壳的设计符合这些严格的分类。该 EX 模块通过一个短转接板直接安装到 V200P 基座定位器上，该转接板在板的背面提供气压，通过 4/20 mA 信号在内部将此压力转换为 3-15 psi 信号，返回到定位器信号隔膜室。不要与 Nema 分类（7 或 9）混淆，这些 FM-CSA、-ATEX 等区域分类/批准均附有相应的证书文件。对于位置反馈，VAC 提供了一个特殊的第三方安装适配器，允许将 EX 反馈直接安装到设备上，从而消除了笨拙的连杆臂和复杂的安装。
