2. Product overview

HMP series probes are humidity and temperature measurement probes with a digital output (Modbus protocol). The probes are designed for demanding humidity and temperature measurement applications. The probes have a two-part structure, with measurement electronics contained in the probe body and sensor(s) in the probe head. The probe body and the probe head are connected by a cable. Length options for this connecting cable depend on the probe model.

The probes are compatible with Vaisala Indigo transmitters. They can also be connected to Vaisala Insight software for conﬁguration, calibration, adjustment, diagnostics, and temporary online monitoring.

3. Installation

When you choose the installation location for the probe, consider the following:

• Verify the operating environment speciﬁcation of the probe model. The probe head typically has a much wider operating temperature range than the probe body.

• If the temperature of the measured environment diers greatly from ambient temperature, the entire probe head and preferably plenty of cable must be inside the measured environment. This prevents measurement inaccuracy caused by heat conduction along the cable.

• Probe mounting options are model-speciﬁc.

Figure 2 Example installation

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 body or probe head.

3 Attach the probe body to a wall or other surface using the two mounting clips (Vaisala

item 243257SP) supplied with the probe. Each clip attaches to the installation surface with one screw (screw hole Ø 4.2 mm).

4 Cable to Modbus master or Indigo transmitter.

CAUTION!

vibration. Use other methods to secure the probe body if necessary. For example, attach the probe body using a cable tie.

The supplied mounting clips are not designed to withstand strong

Chapter 3 – Installation

Vaisala HUMICAPâ Humidity and Temperature Probe HMP3 is a general purpose probe designed for various industrial processes. The probe structure allows for replacing the sensor without tools, making it suitable for applications such as paint booths and other industrial applications where periodic recalibration alone is not sucient for maintaining the probe performance. Other suitable applications include, for example, industrial HVAC systems, cleanrooms, and environmental chambers.

• Operating temperature for probe head −40 … +120 °C (−40 … +248 °F)

• Operating temperature for probe body −40 … +80 °C (−40 … +176 °F)

If purchased with a composite sensor instead of the ﬁeld replaceable HUMICAPâ R2 sensor, HMP3 can use the chemical purge feature. In environments with high concentrations of chemicals and cleaning agents, the chemical purge option helps to maintain measurement accuracy between calibration intervals.

HMP7 supports probe heating. Probe heating heats up not only the sensor, but the entire probe head. When probe temperature is heated above dew point temperature, condensation on the probe can be avoided while measuring the dew point temperature of the process.

• Temperature measurement range −70 … +180 °C (−94 … +356 °F)

• Operating temperature of probe body −40 … +80 °C (−40 … +176 °F)

• Probe heating and sensor warming functions minimize condensation on probe

• Vapor and pressure proof construction

Chapter 3 – Installation

If probe heating is enabled, output parameters that are dependent on temperature measurement (such as relative humidity) are locked whenever probe is heated unless the true temperature of the measured environment is updated to the temperature compensation register of the probe from another measurement instrument (for example, the TMP1 probe). Output parameters such as dew point temperature that can be measured or calculated without this external temperature information are available even without the temperature input.

Vaisala HUMICAPâ Moisture in Oil Probe MMP8 enables fast and reliable measurement of moisture in oil. It uses proven Vaisala HUMICAPâ sensor that was developed for demanding dissolved moisture measurements in transformer and lubrication oils, hydraulic ﬂuids, and other liquids.

MMP8 measures dissolved moisture in oil in terms of the water activity (aw), relative saturation (%RS), and temperature (T). Water activity or relative saturation indicate directly whether

there is a risk of free water formation. This data is relevant in lubrication oil applications where detecting water ingress and preventing free water formation is crucial. The measurement is independent of oil type and age.

WARNING!

has not been exposed to dangerous contamination, and is safe to handle without special precautions.

If you think the device is not measuring correctly, calibration and adjustment is not the ﬁrst thing to do. Check the following ﬁrst:

• Make sure nothing is interfering with the measurement: heat sources, temperature dierences, or condensation.

• Check that there is no moisture on the probe. If the sensor has become wet, wait for it to dry.

• Always wait for the measurement to stabilize.

Calibration means comparing the measurement output of the device to a known reference, such as a known environment in a calibration chamber or the output of a reference instrument. Correcting the reading of the device so that it measures accurately is referred to as adjustment.

When returning a product for calibration or repair, make sure it

6.4.1 Adjustment points and requirements

You can adjust the humidity measurement in 1 ... 5 points, and temperature measurement in 1 ... 2 points. Note the following:

• Humidity adjustment in more than two points is available when using Insight software in Advanced Mode.

• If you are adjusting in more than one humidity point, make sure the ﬁrst two points are at least 10 %RH apart.

• The probe will reject adjustments that are too large, that is, greater than 10 %RH for humidity and 0.5 °C for temperature. If the probe appears to need such a large correction, perform a sensor purge and repeat the adjustment procedure. Make sure the measurement has stabilized and the reference environment is reliable. If the required adjustment is still too large, the probe needs to be serviced by Vaisala.

When adjustment of humidity measurement is necessary, Vaisala recommends adjusting in two points, 11 %RH and 75 %RH. These humidities can be produced using the Vaisala HMK15 Humidity Calibrator. Adjustment of temperature measurement is typically not necessary.

Chapter 6 – Maintenance

6.4.2 Adjusting measurement with Insight software

Problem Possible cause Solution

Measurement output seems incorrect

Probe status indicator LED is red

Values of measurement parameters stop changing for a few minutes

Installation location is not representative of actual conditions you want to measure

Heat conduction along probe head and cable is interfering with measurement accuracy

Probe is in need of adjustment Calibrate and adjust the probe.

Probe is in error state Connect the probe to Insight

Probe is performing a sensor heating function such as chemical purge or waiting for the sensor to cool down

Verify the installation location and relocate the probe if necessary.

software (page 27) and Error messages (page 46).

Wait for the function to complete and measurement parameters to be available again

7.2 Error messages

The error messages are categorized according to the severity of the status:

• Critical errors are fatal to the operation of the device. It may not be able to respond to communication at all, and will not measure correctly.

• Errors prevent normal operation of the device. Depending on the problem, errors may resolve themselves. For example, a completely wet humidity sensor may cause a humidity measurement error.

• Warnings do not prevent normal operation but may indicate possible problems.

• Status indicates a known state of the unit.

A.3 Data encoding

In the data registers, the numeric values are available in one or two formats with separate register addresses: 32-bit IEEE ﬂoating point format and/or 16-bit signed integer format.

HMP3, HMP4, HMP5, HMP7, HMP8, HMP9, MMP8, TMP1 User Guide M212022EN-D

A.3.1 32-bit ﬂoating point or integer format

Least signiﬁcant 16 bits of ﬂoating point or integer numbers are placed at the smaller Modbus address as speciﬁed in Open Modbus TCP Speciﬁcation, Release 1.0. This is also known as "little-endian" or "Modicon" word order. Floating point values are represented in standard IEEE 32-bit ﬂoating point format.

Despite the speciﬁcation, some Modbus masters may expect "big-endian" word order (most signiﬁcant word ﬁrst). In such case, you must select "word-swapped" ﬂoating point format in your Modbus master for the Modbus registers of the device.

A "quiet NaN" value is returned for unavailable values. A quiet NaN is, for example, 7FC00000

; however, the master should understand any NaN value.

hex

A complete 32-bit ﬂoating point or integer value should be read and written in a single Modbus transaction.

A.3.2 16-bit integer format

Some 16-bit integer values in the data registers are scaled to include the necessary decimals. The scaling factors for those values are shown in the register tables.

Table 54 16-bit signed integer format details

Value Description

8002

hex

… 7FFE

… FFFF

hex

Value in range 0 … 32766

Value in range -32766 … -1 (2’s complement)

Value is not available (quiet NaN)

Some values may exceed the signed 16-bit range even in normal operation. To access such values, use the ﬂoating point registers instead.

A.4 Modbus registers

CAUTION!

addresses in actual Modbus messages (Modbus Protocol Data Unit (PDU) are in hexadecimal and start from zero. Subtract 1 from the register number presented in this manual to get the address used in the Modbus message (for example, register number 1 corresponds to address 0

Registers are numbered in decimal, starting from one. Register

in the actual Modbus message).

hex

Appendix A – Modbus reference

Accessing unavailable (temporarily missing) measurement data does not generate an exception. “Unavailable” value (a quiet NaN for ﬂoating point data or 8000

for integer data)

hex

is returned instead. An exception is generated only for any access outside the applicable register ranges.

The response to a write function informs that the function was correctly received by the device. It does not guarantee that the written value was accepted by the device (for example, in case out-of-range values).

To verify that the value was really accepted by the device, read the register value after writing.
