Humidity & Temp Controllers

Product Details:

The ASHE AHT-74 is a micro-controller based Relative Humidity and Temperature Indicator with control outputs, offered in a highly compact, rugged and reliable execution. The instrument has three keys on the front panel, with which the operator can set the parameters and configure the instrument as desired. The instrument accepts RS485 signal from the RH-cumTemperature sensor probe HTP-1 as input signal. The instrument AHT-74 is factory calibrated, so that it doesn't require calibration at the plant site.

The AHT-74 provides four control Relay outputs (two for each parameter), the set points of which may be configured with it's independent Hysterisis value, through the Membrane Keypad on the front panel. The instrument operates on universal AC power supply (90 to 270 V AC, 50/60 Hz) and is offered in standard ¼ DIN panel-mount execution. The instrument has non-volatile memory.

The RH & Temperature Indicating Controller Model: AHT74 is an ideal instrument for Humidity & Temperature measurement and control applications. Other features include it's inherent accuracy and immunity to shocks, dust, ambient temperatures, and humidity. It is available in field-mounting (weather-proof / explosion-proof executions) and standard panel mounting enclosures. Further, the instrument is manufactured using selected high-grade components which guarantee it's functionality and long operational life.

The ASHE Series HTR are a range of micro-controller based instruments for the measurement and retransmission of Relative Humidity and Temperature, offered in a compact and portable execution. The instrument has three control Keys on the front panel, through which the Operator can set the parameters and configure the instrument as desired.

The instrument uses a precision RH+T Sensor and is factory calibrated for accurate display of ambient temperature and relative humidity.

The instrument provides two analog retransmission signals of 4-20 mA DC proportional to the measured Relative Humidity and Temperature for process control or logging purposes. It also offers a RS485 communication signal (on Modbus RTU protocol) of these parameters, for remote monitoring. The instrument operates on 24 VDC and is offered in a rugged polycarbonate enclosure in wall-mount execution. The bright OLED display provides clear indications of the relative Humidity and Temperature values.

Product Details:

The ASHE HTP-1 is a micro-controller based Relative Humidity and Temperature Probe to be used in conjunction with the AH-74, AT-74 and AHT74 Indicator Controllers. The probe is a compact self-contained unit which accurately senses the ambient temperature and relative humidity.

The data is transferred to the Indicator Controllers on RS485 digital signal to eliminate loss of data during transmission. The Probe may be positioned in a suitable location of the chamber and plugged into the Controller located nearby. A Cable of 2 metre standard length is provided with each Probe. Customized lengths can be offered. Power supply to the cable is provided by the host Controller.

The HTP-1 Probe is precision calibrated for relative humidity and temperature. Other features include it's inherent accuracy and immunity to shocks and ambient dust. Further, the instrument is manufactured using selected high-grade components which guarantee it's functionality and long operational life.
