1.2 Description

The head transmitter, type "Wtrans B", designed for industrial applications consists of the
transmitter with integrated transmission unit and an antenna-battery case. The transmitter is
designed for integration into the connection heads, form B. Integration into customer-specific
connection heads is also possible. The antenna-battery case is installed on the connection
head via a thread (M20x1.5).

The measured value is transmitted wireless to the receiver of the Wtrans system, displayed on
the LCD display and provided on the receiver via the RS485 interface as well as an analog out­put. The radio frequency within the ISM band (Industrial, Scientific and Medical Band) is 868.4
MHz. This frequency is almost insensitive to external interferences and allows transmission
even in a rough industrial environment. When using the antenna wall holder with the 3 meter
long cable for the receiver, the maximum open air range is 300 m.

A lithium battery 3.6 V, 2.2 Ah (size AA) is used for the transmitter power supply.
Transmitter (probe) and receiver can be configured with the optional setup program (probe ID,

transmission interval, measuring range and, if necessary, probe type). The configuration data
can be archived on data carriers and printed. Changed parameters can be overwritten again
with the factory settings at any time. The connection between transmitter and PC is estab­lished via a PC interface (USB/TTL or TTL/RS232 converter).

2.1 Rating plate

Position

The rating plate is glued laterally to the transmitter.
The factory set probe ID is additionally stated on a sign fitted on top of the transmitter.

Contents

The rating plate contains important information. This includes, among others:

2 Identifying the instrument version

Description Designation on the rating

Device type Type 707060/8-10/000
Sales No. VARTN 70/XXXXXXXX
Serial No. F-No 0070033801210220006
Voltage supply DC 3.6 V
Probe ID 123
Transmission frequency 868.4 MHz

Device type

Compare the specifications on the rating plate to your order documents. The supplied device
version can be identified using the type key in Chapter 2.2 "Order details", page 10.

Sales No. (VARTN)

The Sales No. provides an unambiguous definition of an article from the catalog. It is impor­tant for communication between the sales department and the customer.

Serial No. (F-No.)

The serial number (F-No.) indicates, among others, the production date (year/week) and the
hardware version number.

Example

plate

Production date

Example: F-No. = 0070033801210220006
The figures concerned are in positions 12, 13, 14, 15 (from the left).
Thus the device was produced in the 22nd calendar week in 2010.

Probe ID

The probe ID is factory set. It must be entered and activated on the receiver to establish com­munication between the probe and receiver. The probe ID can be changed to customer spe­cific requirements using the setup program. The user must exclude that several probes with
identical probe IDs are active.

Transmission frequency

The transmission frequency identifies the frequency and frequency band used by the device
for transmission. In the 868 MHz ISM band (Europe), the transmission is carried out at 868.4
MHz.

3.1 Fitting/exchanging the battery

CAUTION!

Ensure that soiling, moisture and vapors cannot enter the device.
The device could be destroyed.
When inserting/changing the lithium battery, ensure that the device is not exposed to soiling,
moisture and vapors.

CAUTION!

The probe does not function, if the poles are incorrectly connected.
The battery and the probe electronics could be damaged.
Ensure that the poles are correctly connected.

CAUTION!

Incorrect batteries put safety at risk.
The device could be destroyed when using incorrect batteries.
Only use the lithium battery available as accessories.

Power supply of the probe is provided by the included 3.6 V, 2.2 Ah lithium battery inserted in
the antenna-battery case ready for use.

Battery service life depends on the set transmission interval and the ambient temperature: ap­prox. 1 year with the factory-set values (transmission interval 15 s) and room temperature.
