ExPro – Sensor Probes and Thermal Trigger

Key features

ExPro-C: probe for the ExCos-D/RedCos-D transmitter (air temperature and/or humidity)
ExPro-B: probe for the ExBin-D/RedBin-D transmitter (temperature/humidity thermostat)
InPro-C / InPro-B: the same probes for the safe area (InCos-D / InBin-D)
All families in 3 versions: T (temperature only), F (humidity only), TF (combined)
4 probe lengths: 50 / 100 / 150 / 200 mm, plug-in connector
Materials: adapter stainless steel 1.4305/PEEK, housing stainless steel 1.4301, cap AISI 316
ExPro-TT/InPro-TT: stand-alone thermal trigger for fire dampers (see below)

Applications

Air temperature Relative humidity Fire dampers (ExPro-TT/InPro-TT)

ExPro-C can only be used with ExCos-D/RedCos-D, ExPro-B only with ExBin-D/RedBin-D – always 1 probe per transmitter. The probes have no Ex marking of their own (certification is provided by the transmitter).

ExPro-C and ExPro-B (for Ex zones) and their safe-area counterparts InPro-C and InPro-B share the same design (the only difference is the paired transmitter); all families exist in 3 variants according to the measured quantity.

ExPro-C For ExCos-D / RedCos-D

Air temperature and/or humidity

Variant	Measures	Probe lengths
ExPro-CT	Temperature	50 / 100 / 150 / 200 mm
ExPro-CF	Humidity	50 / 100 / 150 / 200 mm
ExPro-CTF	Temperature + humidity	50 / 100 / 150 / 200 mm

ExPro-B For ExBin-D / RedBin-D

Temperature/humidity thermostat

Variant	Measures	Probe lengths
ExPro-BT	Temperature	50 / 100 / 150 / 200 mm

ExPro-BTF	Temperature + humidity	50 / 100 / 150 / 200 mm

InPro-C For InCos-D (safe area)

Air temperature and/or humidity – outside Ex zones

Variant	Measures	Probe lengths
InPro-CT	Temperature	50 / 100 / 150 / 200 mm
InPro-CF	Humidity	50 / 100 / 150 / 200 mm
InPro-CTF	Temperature + humidity	50 / 100 / 150 / 200 mm

Temperature/humidity thermostat – outside Ex zones

Variant	Measures	Probe lengths
InPro-BT	Temperature	50 / 100 / 150 / 200 mm
InPro-BF	Humidity	50 / 100 / 150 / 200 mm
InPro-BTF	Temperature + humidity	50 / 100 / 150 / 200 mm

ExPro-TT / InPro-TT Accessory – ExPro-TT for ExMax/RedMax-BF, InPro-TT for InMax-BF

Thermal trigger for fire dampers – not a probe for a transmitter

Model	Length	Trigger temperature	Note
ExPro-TT-72 / InPro-TT-72	65 mm	Tf1 +72 °C (ambient) / Tf2 +71 °C (duct)	ExPro-TT → ExMax/RedMax-BF; InPro-TT → InMax-BF
ExPro-TT-72-L90 / InPro-TT-72-L90	90 mm	Tf1 +72 °C / Tf2 +71 °C	ExPro-TT → ExMax/RedMax-BF; InPro-TT → InMax-BF

Special versions to order: ExPro-TT-...-S1 (Ex-e cable gland M25×1.5 mm instead of the standard M12) and ExPro-TT-...-S6 (extended 1.5 m cable).

ExPro-TT is exclusively an accessory for ExMax-...-BF and RedMax-...-BF actuators, InPro-TT exclusively for InMax-...-BF actuators (see the ExMax page) – power is supplied only by a -BF type actuator; it does not work on its own. It is not a probe for ExCos-D or ExBin-D.

Designation key

What the suffixes mean

C vs. B

C = for ExCos-D (modulating transmitter), B = for ExBin-D (switching thermostat).

Ex vs. In

Ex = for Ex zones (1, 2, 21, 22), In = the same probe for the safe (non-Ex) area, for InCos-D/InBin-D transmitters.

T / F / TF

T = temperature only, F = humidity only (Feuchte), TF = both combined.

Temperature Trigger – thermal trigger for fire dampers: ExPro-TT exclusively for ExMax/RedMax-BF, InPro-TT exclusively for InMax-BF.

ExPro-C / ExPro-B – production quality

BVS ATEX ZQS/E136

C/B probes have no type certificate of their own – intrinsic safety and Ex marking are ensured by the connected ExCos-D/ExBin-D transmitter. The manufacturer has a certified production quality system (DEKRA).
