ADHT-Ex露点传感器是英国阿尔法公司一款防爆露点传感器，3限制、24V回路供电4-20mA信号输出。露点传感器自身防护等级在IP65，能够在恶劣场合使用。
The Alpha Moisture Systems Model ADHT-Ex is a 3 wire, 24V powered 4-20mA dewpoint transmitter. The unit is fully self contained in a robust casing with weatherproof protection to IP65, making it ideal for use in heavy industrial environments.
ADHT-Ex操作非常简便。
Designed with the operator in mind, Model ADHT-Ex is extremely easy to use and the digital dewSMART technology ensures accurate and reliable readings with little or no maintainance.
ADHT适用于防爆场合，防爆等级Ex ia IIC T6，本安型传感器配合MTL安全栅可在危险区域使用。
Model ADHT is certified intrinsically safe to Ex ia IIC T6 for use in hazardous areas using an MTL 2441B signal isolator for 110V / 240V AC operation or MTL 5042 for 24V DC operation.
传感器的测量范围从-110oC 覆盖到 +20oC露点。
Various ranges are available covering an overall range from -110oC to +20oC dewpoint. The Model ADHT-Ex derives its power directly from the signal isolator and it is configured to give a linear 4-20mA signal for the chosen range.

AMT露点变送器
Model AMT Dewpoint Transmitter is a two wire 4-20mA loop powered unit, used for continuous measurement of moisture levels in gases and compressed air, which will output a linear 4-20mA signal corresponding to the dewpoint temperature. The Model AMT dew-point transmitter can also be factory configured to output a 4-20mA linear signal for any other moisture unit for example, ppm(v), ppm(w), g/m3 or lb/MMSCF.

The Ultra High Capacitance sensing element is long lasting and offers excellent sensitivity, repeatability and response speed. Each unit is supplied with a Certificate of Calibration, traceable to International Humidity Standards, validating accuracy to ±2oC dewpoint.

The built in Automatic Calibration (AUTOCAL) feature comes as standard on all the Model AMT range, this allows the user to carry out a field calibration, span check. The AUTOCAL feature is operated by means of two small button switches on the side of the transmitter enclosure (see picture). To avoid tamper, the switches are locked in normal use and can only be activated by following a certain routine.

The integral RISC microprocessor circuitry of the Model AMT transmitter allows high resolution with advanced self diagnostics for fault conditions. It also enables periodic re-calibration of the moisture sensor, storing calibration data within the fully self contained unit. Loop powered by a 7V to 28V dc source, the Model AMT transmitter will provide a linear 4-20mA signal over the chosen range.

The mechanics of the Model AMT transmitter have been designed to cope with extreme environmental conditions. The rugged stainless steel construction offers protection to IP66 (NEMA4X), with the transmitter electrical connections made via a secure industrial connector.

Model AMT transmitter can withstand 35,000 kPa (350bar) maximum pressure and by employing a low resistance cable, the transmitter can be located at significant distances, in excess of 1000 metres, from the control room. Designed with the operator in mind, for reliable and accurate measurements, the Model AMT transmitter is extremely easy to install and operate, requiring little or no maintenance.

The Model AMT transmitter is supplied with a Certificate of Calibration, an instruction manual and 2m connecting cable as standard.
