Description

Ultra 1000 series is a microprocessor based addressable sensor for detection of Hydrogen Sulfide in ambient air. The self- contained sensor features user friendly interface and menu driven calibration procedure and configuration.

The complete sensor consists of a stainless steel sensor head assembly, a user connection board and a transmitter board assembly. All of the sensor electronics are enclosed in an explosion proof instrument box. The unit’s modular design allows easy maintenance, troubleshooting and high reliability.

The unit provides a 4-20mA signal proportional to 0 to 100% of the detection range. In addition the sensor may be addressed via MODBUS RTU interface. The MODBUS output provides sensor status, alarm & fault conditions. Alarm levels can be programmed via MODBUS RTU or via magnetic switch on the face of the transmitter board assembly.

Ultra 1000 can be calibrated in less than 2 ½ minutes. The calibration and the set-up parameters are retained in a non-volatile memory.
