in transport, installation, operation, maintenance and repair. The user manual may not be used for the

purposes of competition without the written consent of E+E Elektronik® and may not be forwarded to

third parties. Copies may be made for internal purposes. All information, technical data and diagrams

included in these instructions are based on the information available at the time of writing.

Please find this document and further product information on our website at

www.epluse.com/htp201.

1.1 Explanation of Symbols

This symbol indicates safety information.

It is essential that all safety information is strictly observed. Failure to comply with this information can

lead to personal injuries or damage to property. E+E Elektronik® assumes no liability if this happens.

This symbol indicates instructions.

The instructions shall be observed in order to reach optimal performance of the device.

1.2 Safety Instructions

1.2.1 General Safety Instructions

■ Avoid any unnecessary mechanical stress and inappropriate use.

■ When replacing the filter cap make sure not to touch the sensing elements.

■ The device must be operated with the filter cap on at all times.

■ Installation, electrical connection, maintenance and commissioning shall be performed by qualified

personnel only.

■ Use the HTP201 only as intended and observe all technical specifications.

■ Do not use HTP201 in explosive atmosphere or for measurement of aggressive gases.

1.2.2 Intended Use

The HTP201 is intended for highly accurate and cost effective humidity (RH) and temperature (T)

measurement in demanding process applications. The RH and T measured data is available on two

analogue outputs for voltage (0 - 1 V, 0 - 5 V or 0 - 10 V) or current (4 - 20 mA, 2-wire). In addition, the

HTP201 has a passive T output (4-wire), a wide temperature and supply voltage range, making it a

universally applicable probe.

The use of the HTP201 in any other way than described in this manual bears a safety risk for people

and the entire measurement installation and is therefore not allowed.

The manufacturer cannot be hold responsible for damages as a result of incorrect handling, installation,

and maintenance of the equipment.

In order to avoid damage to the instrument or health hazards, the measuring equipment must never be

manipulated with tools that are not specifically described in this manual.

The sensor may only be utilized in accordance with the conditions defined in the technical data.

Otherwise, measurement inaccuracies will occur and equipment failures cannot be ruled out.

The steps recommended by the manufacturer for installation, inspections and maintenance work must

be observed and carried out for the safety of the user and for the functionality of the equipment.

Unauthorized product modification leads to loss of all warranty claims. This may be accomplished only

with an explicit permission of E+E Elektronik®!

3 Product Description

3.1 General

The HTP201 is a robust probe for relative humidity and temperature measurement. Its IP65 rating,

the E+E proprietary protective sensor coating and encapsulated electronics make it ideal for

highest requirements. The HTP201 is typically implemented in demanding process and climate

control applications like in agriculture, life stock, food, pharma or clean rooms. Its stainless steel or

polycarbonate enclosure and integrated cable or a threaded connector together with the wide choice of

filter caps make it a versatile probe tackling even challenging applications. Installation is simplified by

various mounting options which are supported by E+E accessories.

4 Installation

4.1 Wall and Ceiling Mount

Best measurement performance is achieved when the entire probe is located inside the environment to

be monitored.

In such a case, the HTP201 may be for instance fixed onto a wall with the mounting clip HA010211

(for polycarbonate) or HA010225 (for stainless steel, both not included in the scope of supply, see data

sheet “Accessories”), or freely hang from the ceiling on the connection cable.

Fig. 3 Optional wall and ceiling mount (ordering code HA010211)

4.2 Duct Mount

The probe also can be installed into a duct using the plastic flange HA010214 or the stainless steel

flange HA010201 (not included in the scope of supply, see data sheet “Accessories”).

4.3 Recommendations for accurate Humidity and Temperature

Measurement

■ In case the HTP201 probe is not entirely located in the environment to be monitored, large

temperature differences along the probe will lead to temperature gradients. These will have an

influence on the accuracy. Therefore, it is of paramount importance to minimize the temperature

gradients. The biggest part of the probe shall be located in the target environment and the rest shall

be thermally well insulated.

User Manual HTP201 Humidity and Temperature Probe with Analogue Outputs

■ For outdoor applications the HTP201 shall be equipped with a radiation shield (HA010502) which

provides protection from rain, snow and ice. This also causes a natural ventilation which largely

prevents overheating of the probe in the sun and thus a distortion of the measured values.

■ Best accuracy is achieved with a velocity of min. 0.2 m/s of the air surrounding the probe. Depending

on the installation position, flow direction and flow velocity, the accuracy may decline. The following

table gives a concise overview. Please note that the vertical positioning with the sensing element

upside is the most sensitive one concerning accuracy. Because of possible self heating due to the

sensor electronics, it is crucial to have the indicated air flow velocity.

> 0.2 m/s > 0.2 m/s

Tab. 1 Mounting position, air velocity and accuracy

5 Maintenance and Service

HTP201 does not require any special maintenance, nevertheless for high accurate measurements

especially over wide RH and T ranges it is recommended to calibrate the probe every 12 months. If

needed, the enclosure or the sensing element may be cleaned as described below.

5.1 Cleaning

Use a damp soft cloth to remove deposits of dust or dirt from the exterior of the probe. Do not use any

solvents or abrasive cleaning agents.

In case of dusty, oily and polluted environment:

■ Use a damp soft cloth to remove deposits of dust or dirt from the exterior of the probe. Do not use

any solvents or abrasive cleaning agents.

■ The filter cap shall be replaced once in a while with an E+E original one (see below).

■ If needed, the sensing element of the humidity probe can be cleaned by the user (see cleaning

instructions - www.epluse.com/cleaning-instructions).

5.2 Filter Cap Replacement

In a dusty or polluted environment it might be necessary to replace the filter cap once in a while. In most

of the cases, a clogged filter shows visible contamination or dirt. Longer response time of the humidity

measurement also indicates a clogged filter cap. In such cases, replace the filter by a new, original one,

see chapter 5.5 Spare Parts.

Procedure

■ Turn the filter cap counter-clockwise for removing it.

■ Install the new filter cap finger tight by turning it clockwise.

While replacing the filter cap take very good care to not touch or rub the sensing element.

5.3 Protection during Site Cleaning Operations

During site cleaning or sterilization process, if the HTP201 remains on the measuring site the sensing

head can be protected with the optional protection cap for 12 mm (0.47") probe (HA010783, see

datasheet “Accessories”).

In case the probe is removed from the site, it is recommended to apply the protection cap for the M12

cable socket (HA010781) and the one for the HTP201 M12 plug of (HA010782).
