1.2 SENSOR INTERFACE
The WaveTherm modules are designed for use in a varied environment. They are therefore available with
several types of temperature sensors offering performance characteristics enabling maximum coverage of
the module's scope of application.
 WaveTherm – DALLAS: turnkey module supplied prewired to the probe via a connector.
 WaveTherm – PT1000: turnkey module offering better performance than the WaveTherm –
DALLAS option. As standard, the WaveTherm modules are supplied with a PT1000 probe directly
connected to the module (no connectors). However, when requested by the customer, it is
possible to supply these modules with a BINDER series 720 type connector.
 WaveTherm – PT100: module intended for use by assemblers. Supplied without probe, with
socket connector on the module side and a plug-in connector on the probe side.
1.2.1 WAVETHERM – DALLAS
This module is designed for a maximum of two temperature probes type DS18B20 (or DS18S20) from
DALLAS. The DALLAS 1-wire type probe contains an internal 12-bit convertor.
Each external probe is connected to a cable outside the casing. This cable is equipped with a 3-pin connector
type BINDER (series 719).
BINDER series 720 type connector
Automatic identification of the temperature probes enables memorisation of the probe's ID. This phase is
completed automatically when the module is switched on and may also be enabled with a specific radio
request.
The module returns a radio signal with the probe's ID (see chapter 2.1.2)
