Multi-point Temperature Transmitter For Bitumen Measuring in Vietnam

The multi-point temperature transmitter is capable of measuring the temperature at various liquid height points within pools and tanks based on RTD or thermocouple working principle . It offers direct connectivity to computer interface cards, control instruments, intelligent instruments, or PLCs, allowing for temperature signal output via 4-20mA and RS485.

1) What is the application of the multipoint RTD and multipoint thermocouple ?

• Temperature measurement at various height points in large oil tanks at oil fields and refineries, encompassing measurements at different liquid point locations within vertical tanks, horizontal tanks, storage tanks, and floating roof tanks.
• measurement of distinct liquid levels and liquid point locations within the third section of various storage tanks at chemical plants.
• measurement at differing material point locations within large granaries.
• applications necessitating multi-point temperature measurements at varied heights and intervals.

2)What is the features of the muitipoint temperature sensors ?

• The product employs a multi-point semiconductor temperature measurement system, wherein each temperature point is interconnected via a bus, thereby eliminating the complications associated with lead wires from multiple thermal resistance measuring devices (thermocouples).
• The quantity and spacing of temperature points can be configured at will, the length (height) of the tube probe may extend up to 30 meters, and the total number of temperature measurement points can reach a maximum of 120.
• This device is constructed from high corrosion-resistant materials, making it suitable for a wide range of working conditions..
• It features a digital local display and an RS485/MODBUS intelligent communication interface, facilitating remote data transmission..
• The system supports two-way standard analog signal transmission and the MODBUS communication protocol, thus allowing for easy interfacing with DCS, PLC, and various types of host computers, with a single bus capable of connecting up to 127 instruments
