Safety

The product delivered to you has been tested for safety and approved as

shipped from the factory. Note the following precautions:

WARNING

Ground the product, and verify outdoor installation grounding

periodically to minimize shock hazard.

CAUTION

Do not modify the unit. Improper modification can damage the product

or lead to malfunction.

ESD Protection

Electrostatic Discharge (ESD) can cause immediate or latent damage to

electronic circuits. Vaisala products are adequately protected against

ESD for their intended use. It is possible to damage the product,

however, by delivering electrostatic discharges when touching,

removing, or inserting any objects inside the equipment housing.

To make sure you are not delivering high static voltages yourself:

- Handle ESD sensitive components on a properly grounded and

protected ESD workbench.

- When an ESD workbench is not available, ground yourself to the

equipment chassis with a wrist strap and a resistive connection cord.

- If you are unable to take either of the above precautions, touch a

conductive part of the equipment chassis with your other hand before

touching ESD sensitive components.

- Always hold component boards by the edges and avoid touching the

component contacts.

CHAPTER 2

PRODUCT OVERVIEW

This chapter introduces the product features and options.

Introduction to HMP60 and HMP110

Vaisala Humidity and Temperature Probes HMP60 and HMP110 are

simple and cost-effective humidity transmitters suitable for volume

applications, integration into other manufacturers’ equipment, incubators,

glove boxes, greenhouses, fermentation chambers, and data loggers.

HMP60 uses the interchangeable Vaisala INTERCAP® sensor. No

recalibration is required after sensor replacement.

HMP110 uses the Vaisala HUMICAP 180R® sensor for increased

accuracy. The HMP110 requires calibration after sensor replacement.

This can be done on the serial line using the optional Vaisala USB cable.

Installation Accessories (Optional)

Probe Mounting Clamp

The optional mounting clamp makes it easy to install the probe on the

wall of the measurement environment. The probe can be detached for

calibration simply by loosening the lower screw.

Probe Mounting Flange

The probe mounting flange is a silicone flange can be used to hold the

probe in a through-wall installation. The flange is a general purpose

mounting accessory for Ø 12mm probes, and comes with a sealing plug

for coaxial cables that is not needed when the flange is used with HMP60

and HMP110.

Loop Power Converter

The loop power converter is an open frame module that converts one

0 ... 2.5 VDC voltage output to a 4 ... 20 mA current output. To use the

loop power converter module, the probe:

- must be in the analog output mode

- the desired quantity must be on channel 1

- channel 1 must be scaled to 0 ... 2.5 V

Wiring instructions are provided in section Wiring with the Loop Power

Converter on page 22.
