The Temperature Multiplexer is a multi-spot temperature transmitter capable of accepting up to 16 RTD inputs, intended for use within hazardous areas. It presents a unified Modbus, GPU or Current Loop interface to the control systems, for larger numbers of RTDs, multiple units can be multi dropped seamlessly onto the same field bus as other devices such as level gauges.
Used in conjunction with our Mini Receiver and LMS software the TM188 provides a simple, proven skin temperature monitoring system used during the cooldown commissioning phase of dozens of LNG tanks the world over.
- Multi-spot temperature transmitter capable of accepting up to 16 RTD inputs in a single unit.
- Capable of multi-dropping on to a field bus to support more temperature sensors.
- Performs measurements locally, and can share level gauge buses reducing the amount of expensive cabling required.

No other analogue-digital multi-channel interface holds certification for IECEx, ATEX, and GOST for Zone 1. Produced in the UK from a manufacturer with over 15 years experience of designing and manufacturing solutions for explosive atmospheres.
The unit is ATEX, IECEx and GOST approved for installation into a Zone 1 hazardous area. The unit has many applications for accurate measurement within a hazardous or non-hazardous area but has been specifically designed for temperature measurement requirements within a tank gauging system designed for bulk measurement of oil and gas. Petroleum storage installations such as Refineries, Marketing / Distribution Terminals, and Liquified Gases.
Natural Gas (LNG) storage facilities use these devices for skin temperature measurement. The two field bus ports help to support the redundant architectures often demanded by LNG applications, and each port can be polled simultaneously for data by two independent host systems if necessary. Field bus interfaces are available for a range of host systems.
