module provides a digital RS-485/Modbus RTU and three freely conﬁgured analog output

channels.

Installing Module

The measurement probe with cable is attached to the component board at

Installing Probe

HMM170 probe is designed for applications that involve constant high humidity or rapid

changes in humidity, such as drying and test chambers, combustion air, and other humidiﬁers

and meteorological measurements, where measurement performance and chemical tolerance

are essential.

Figure 2 HMM170 Probe Head Dimensions

1. Mount the probe head horizontally to prevent any water condensing on the probe head

from running to the sensors.

2. Let the cable hang loosely to prevent condensed water from running along the cable to

the probe head.

3. Seal the cable pass-through using the probe mounting ﬂange or silicone sealant.

If the temperature of the measured environment diers greatly from ambient

temperature, the whole probe and preferably plenty of cable must be inside the

process. This prevents measurement inaccuracy caused by heat conduction along

the cable.

Conﬁguration

To conﬁgure HMM170, use Vaisala Insight Software. You can connect the module to Vaisala

Insight software using a Vaisala USB cable (no. 219690).
